This restores the prior path where angle_enable_trace would let ANGLE
write a debug.txt file without needing environment variables or
run-time annotator attachments.

Deferred clears are not collected when syncing the READ framebuffer.
Prior to this change, we had in FramebufferVk::syncState:

    if (READ && deferredClears.any())
    {
        flushDeferredClears();
    }

However, this is impossible / unnecessary:

- Every operation whose syncState (for the DRAW framebuffer) collects
  deferred clears will flush the deferred clears.  In fact, it's an
  error for the next operation's syncState to encounter pre-existing
  deferred clears.
- The READ framebuffer is synced before the DRAW framebuffer.  This
  makes it impossible for there to be deferred clears when READ is
  synced.

It may be necessary to swap the order in which the READ and DRAW
framebuffers are synced.  See http://anglebug.com/5266.  In that case,
if the READ and DRAW framebuffers are identical:

- The DRAW framebuffer's sync will collect deferred clears.  The READ
  framebuffer's sync will see deferred clears, but it must not flush
  them!

Change ANGLE to dynamically load either EAGL (OpenGLES) or CGL (OpenGL)
depending on both compile and runtime configurations.
    Intel Mac -> CGL

    iOS Device -> EAGL
    Apple Silicon Mac -> CGL
    Apple Silicon Mac Catalyst (with Mac app) -> CGL
    Apple Silicon Mac Catalyst (with iOS app) -> EAGL

The trickiest bit is Apple Silicon Mac Catalyst, which depends on the
type of the application it is attempting to run. In that case ANGLE must
compile both the CGL and EAGL interfaces and then pick one to use after
launch.

Take the following scenario:

  1. glClear
  2. glScissor(half of framebuffer)
  3. glDrawArrays

The clear in step 1 is deferred.  When FramebufferVk::syncState is
called in step 3, the deferred clear was applied using
vkCmdClearColorImage because the draw call is scissored.  This causes
loadOp=LOAD to be used after the clear because the render pass is
started too small (the same size as the scissor).

This change makes scissored operations also take advantage of
loadOp=LOAD with deferred clears.  A number of changes are made to this
effect:

- FramebufferVk::syncState no longer limits collecting deferred clears
  to no-scissor.
- FramebufferVk::startNewRenderPass automatically expands the render
  area to full size if it's clearing any attachment.
- A number of bugs are fixed where FramebufferVk::flushDeferredClears is
  called with the scissor area.  Instead, flushDeferredClears now
  unconditionally uses the complete render area.  Note that these bugs
  didn't have symptoms as "scissor" and "deferred clears" were mutually
  exclusive.

Add support for GL_EXT_copy_image which allows
image data transfer between image objects.
This is implemented by using the vkCmdCopyImage
API call.

This test would create an sRGB format texture without
checking for the GL_EXT_texture_sRGB extension. Skip
the test if it is not supported.

This is a reland of e70f6aa6

Original change's description:
> ANGLE_platform_angle_device_context_volatile_* extensions
>
> Change from Kimmo Kinnunen downstream:
> https://bugs.webkit.org/show_bug.cgi?id=216106
>
> Add two extensions for EAGL and CGL backends to declare the
> underlying platform context being "volatile". It means that
> the thread-global current context is being modified behind
> ANGLE. If ANGLE context is marked volatile for a particular
> API, it will sync the underlying context for every EGL
> function that needs the context. Most intuitive use is
> for the client to call eglMakeCurrent before calling any
> gl function if the client knowns the platform state might
> be dirty.
>
> Implement eglReleaseThread for EAGL and CGL backends.
> Releasing thread will unset the platform current context.
>
> Fix a bug of omitting EGL_ANGLE_device_eagl from being
> advertised.
>
