Dependencies seem to be incorrectly tracked in some Intel OpenGL
drivers (on macOS specifically), causing crashes in glDeleteTextures
if a GL command buffer is being constructed where those textures are
destinations of CopyTexImage2D/CopyTexSubImage2D. Work around this bug
by flushing before texture deletion if CopyTex{Sub}Image have been
called recently. The tracking is only done on a per-context rather
than a per-device basis, but seems sufficient to work around the
problem as identified.

Tested both with new ANGLE test on affected hardware, and in WebKit's
ANGLE backend for WebGL. Works around the crash reported in
https://bugs.webkit.org/show_bug.cgi?id=205707 .

In https://crrev.com/c/1838418 I added the ability to disable
ARB_texture_rectangle so that we can use it in the WebGL implementation
but disable it when compiling user shaders. Unfortunately disabling
and re-enabling the extension causes the shader translator to be
reinitialized which turns out to be more expensive than the actual
work of shader translation, at least for small shaders. It's slow enough
to cause timeouts in WebKit's WebGL conformance test runs.

This introduces an alternate method of disabling ARB_texture_rectangle
in the translator which is much faster because it avoids reinitializing
the translator.

This fixes a crash (preceeded by Vulkan validation errors) when running
the following test:

--gtest_filter=dEQP.KHR_GLES31/core_texture_storage_multisample_FunctionalTests_blitting_multisampled_depth_attachment* --use-angle=vulkan

The problem is that GraphicsPipelineDesc::updateRasterizationSamples()
is rarely called (e.g. glBindFramebuffer).  The above dEQP test changes
between draw attachments that do and don't have multisampling enabled.
The number of samples is set (the first time) to have multisampling
enabled, and never changed, even though other attachments don't have
multisampling.

FramebufferVk::syncState() now calls updateRasterizationSamples().  That
fix uncovered a latent problem: when an application destroys all
framebuffers (including the draw framebuffer), the ContextVk still
points at the old draw framebuffer's FramebufferVk (now freed).  This
is fixed with new plubming to clean-up ContextVk::mDrawFramebuffer.

This change moves driver uniforms to a set with a lower id than the one
that includes (emulation) transform feedback buffers.  Imagine the
following:

- Program 1 with xfb: UniformsSet: 1 VS uniforms buffer, 1 FS uniforms
  buffer, 1 xfb buffer
- Program 2 without xfb: UniformsSet: 1 VS uniforms bufer, 1 FS uniforms
  buffer.

Previously, UniformsSet was index 0, and DriverUniformsSet was index 3.
When switching from Program 1 to Program 2, the layout of UniformsSet
changes, which means every subsequent set needs to be rebound.  This is
a Vulkan pipeline layout compatibility rule.  This is done with
invalidateCurrentTextures() and invalidateCurrentShaderResources()
already when handling gl::State::DIRTY_BIT_PROGRAM_EXECUTABLE.  The bug
is that the driver uniforms are not invalidated.

This is normally not an issue, because usually when switching from
Program 1 to Program 2, transform feedback is paused, and this state
change does invalidate driver uniforms.  However, the following scenario
doesn't do this:

- Begin Xfb
- Pause Xfb
- Use Program 1
- Draw
- Use Program 2
- Draw
- End Xfb

There is no driver state change between the two draw calls, which means
the second draw will attempt to draw using the driver uniforms bound for
the first draw call.  There is a Vulkan validation error here due to the
above pipeline layout validation rule.

The issue manifests itself only when the second draw call actually uses
driver uniforms, as otherwise that set is inactive and not validated;
i.e. when line raster emulation is used.

In summary, the validation error manifests itself when:

- Transform feedback and line raster both use emulation
- Transform feedback is paused
- A draw with an xfb program is followed by a non-xfb program
- The second draw is a line draw

A test is added for this.

The solution is to reorder the sets so that DriverUniformsSet is placed
before UniformsSet.  This way, changes to the layout of UniformsSet
don't invalidate DriverUniformsSet.

In fact, based on the above, any change in the layout of the program
should have required an invalidation of the driver uniforms.  This bug
is probably masked by the fact that
ContextVk::handleDirtyDescriptorSetsImpl() always rebinds the graphics
driver every time any descriptor set needs rebinding.  That should be
removed in a follow up change.

A flag is added to the translator to disable generation of Bresenham
line raster emulation code when the Bresenham line raster Vulkan
extension is present.  This is primarily for the sake of conversion of
line raster emulation condition to specialization constant:

- Avoid dead SPIR-V code in every shader
- Avoid ANGLEUniforms being active in every shader stage even if it's
  not used anywhere but in line raster emulation.
- Optimize SPIR-V transformations by both having fewer instructions to
  iterate through, and to avoid generating line raster patches.
- Reduce the severity of anglebug.com/4251 where the location assignment
  of ANGLEPosition can incorrectly overlap a varying array or struct, by
  making only platforms without Bresenham extension afflicted by the
  bug.

After vertex buffer's attribute is converted and stored in conversion
buffer. Binding the same attribute to another buffer, then binding it
back to previous buffer will result in previous conversion
information lost. The conversion method would skip the conversion due to
buffer's content hadn't been changed, however it didn't reuse the old
conversion result.

This CL also changed the way binding offset is used in Metal backend.
- Previous, the offset would be assigned to the offset field of
  MTLVertexAttributeDescriptor, then the buffer would simply be bound to
  the command encoder with offset=0
  i.e. setVertexBuffer(buffer, index, 0)
- However this approach has several disadvantages. Since Metal doesn't
  allow MTLVertexAttributeDescriptor's offset to be larger than the
  vertex attribute's stride, the old approach would force the back-end
  to convert the attribute and store in conversion buffer.

New approach:
- MTLVertexAttributeDescriptor's offset will be zero. The offset will be
  used to bind the buffer itself to the render command encoder.
  i.e. setVertexBuffer(buffer, index, offset)
  This way the "offset <= stride" restriction no longer exists. The only
  restriction is the offset must be multiple of attribute's size.

Added 3 new tests:
- SimpleStateChangeTest.RebindTranslatedAttribute
- VertexAttributeTest.DrawWithLargeBufferOffset
- VertexAttributeTest.DrawWithLargeBufferOffsetAndLessComponents

The code that patches the line raster emulation directive assumed both
vertex and fragment shaders would be present.  This is invalid if only a
vertex shader is present.

This change adds the directive to any stage that's available.  This
includes the possibility of a missing vertex shader also, which can be
useful for separable shaders and program pipeline objects.
