As an Android GLES driver on top of Vulkan, ANGLE must pre-rotate
rendering on behalf of the application.  This involves modifying the
vertex shader to multiply gl_Position with a mat2 "rotation matrix".
Not doing so means that SurfaceFlinger (SF) will perform a costly
rotation blit before presenting every image.  Setting
WindowSurfaceVk::mPreTransform to mCurrentTransform tells SF to not do
the blit.

When the surface is rotated 90 or 270 degrees, the width and height
must be swapped for:

- The swapchain images, and for any depth, stencil, and/or multisample
  attachments used with the swapchain image.

- The viewport, scissor, and render area.

Because the Metal back-end shares the TranslatorVulkan, it will define
the same preRotation (mat2) DriverUniform that is used for Vulkan.

commit_id_.py is capable of generating the default commit.h.
This makes it so we always take a single path in gn.

Remove the existing commit.h and generate it into the root
generation folder (not the id subfolder) because Android blueprints
can't handle generating into subfolders that don't exist.

Make the <angle_dir> argument capable of taking a filename or
directory name. This allows us to pass the .git/HEAD file which is
a gn input.  Android blueprints require all paths used as input
or output to a script are listed as inputs or outputs in the genrule.

With this initial implementation, it's possible to get precision
qualifier mis-matches in the generated GLSL 4.50. According to the
spec this is allowed. From GLSLangSpec 4.50 section 4.7 "Precision and
Precision Qualifiers":

For the purposes of determining if an output from one shader stage
matches an input of the next stage, the precision qualifier need not
match.

However, when converted to SPIR-V and run through the shader validation
any mismatches will cause shader validation errors. Initially just
ignoring those errors with this commit.

This portability feature allows a single T-Rex capture done on Vulkan
to work seamlessly on the ANGLE GL back-end and the WGL-loaded NVIDIA
OpenGL driver.

Previously the uniform locations would not be consistent between ANGLE
and a native driver. And incompatiblities would trigger error messages
between ANGLE back-ends.

Will allow us to compare ANGLE performance vs the native driver using a
capture.

Example captured calls:

    glLinkProgram(gShaderProgramMap[3]);
    UpdateUniformLocation(gShaderProgramMap[3], "s_texture", 0);

Use the new combiners functions added in an earlier CL. Makes it easy
to maintain bigger lists of test combinations.

Also a few other changes:

 - removes some D3D9 perf testing since we don't maintain this config
 - removes the "validation only" tests. these were mostly redundant
 - makes the tests permutation combinations more consistent

Rolling ANGLE into AOSP is done with an @google.com account so we need
to have @google.com accounts in the OWNERS file to land rolls.

Will add more @google.com accounts if this is successful.

This is a large refactor that replaces instances of "GLint location"
for uniform locations with "UniformLocation location". This boxed type
is similar to the ResourceID types that we use to capture resource IDs
more easily. Eventually this will give us a more portable replay.
