According to the EXT_color_buffer_half_float spec:

"Dependencies on OES_texture_half_float

    If OES_texture_half_float is not supported, then all references to
    RGBA16F_EXT, RGB16F_EXT, RG16F_EXT, R16F_EXT, HALF_FLOAT_OES and
    half should be ignored.

    If OES_texture_half_float is supported, textures created with:

        <internalformat> = RGBA
        <format> = RGBA
        <type> = HALF_FLOAT_OES

    are renderable."

This fixes 4 viz_unittests when running with SwANGLE:
    All/GLI420ConverterPixelTest.ScaleAndConvert/0
    All/GLI420ConverterPixelTest.ScaleAndConvert/1
    GLScalerPixelTest.Example_ScaleAndExportForScreenVideoCapture

The original attempt at landing this change
(https://chromium-review.googlesource.com/c/angle/angle/+/2489726)
was reverted due to dEQP failures on the Metal backend. After some
investigation, it was decided to simply disable the 2 offending

This change builds on vertex attribute aliasing SPIR-V tranformation for
non-matrix types to add support for matrix attribute types.  This is
done by turning every matrix attribute declaration into multiple vector
attribute declarations, and reusing the same mechanism for resolving
aliasing between non-matrix types.

Take the following example:

    attribute mat4 a; // location 0
    attribute vec3 b; // location 1

    attribute mat3 c; // location 1
    attribute vec4 d; // location 2

The shader is modified as such:

    attribute vec4 a_0; // location 0
    attribute vec4 a_1; // location 1
    attribute vec4 a_2; // location 2
    attribute vec4 a_3; // location 3

    attribute vec3 c_0; // location 4
    attribute vec4 d;   // location 5
    attribute vec3 c_2; // location 6

    mat4 a;
    mat3 c;

and in the beginning of main(), the following code is inserted:

    a = mat4(a_0, a_1, a_2, a_3);
    c = mat3(c_0, d.xyz, c_2);

The shader continues to use a and c as before.

Previously ANGLE would error out when both the enviornment and
the command line args are specified at the same time. Because
the perf bots use both at once we need to handle the conflict
in the same way as the prior test runner does. In this case
the command line takes precedence over the environment.

Initial implementation that supports float and vecN types.  In this
case, every attribute occupies a single location.  When two attributes
alias, they are either the same size, or one is bigger than the other.

Take the following example:

    attribute vec3 a; // location 0
    attribute vec3 b; // location 0

    attribute vec4 c; // location 1
    attribute vec2 d; // location 1

The shader may access either a or b (but not both).  Similarly, it can
access either c or d (but not both).  The shader can be modified such
that:

- f(b) is replaced with f(a).
- g(d) is replaced with g(c.xy).
- b and d are removed

As a result, there are no longer any aliasing attributes.  In other
words, when attributes alias, the larger attribute can be retained and
the other attributes can be replaced by selecting the appropriate number
of components from the retained attribute.

The robustness spec states that all GL calls should generate context
lost errors when the context is lost. This behaviour was lost due to
some context lookup optimizations but can be re-added at no cost by
updating the autogenerated entry points.

Updated the ContextLostTest to cover the repeated error generation
behaviour.

There are cases where we know that the next draw operation will fully
initialize a texture/renderbuffer and we can save the robust resource
init cost.

Default all resource init state to Initialized, any redefinition will
set it back to MayNeedInit.

After setting an individual texture image to initialized, check if
all images are now initialized and update the TextureState::mInitState
to match. The cost of this check is only performed after initializing
an image and allows future init checks to be faster.

Working on enhancing worker thread to completely own primary command
buffers. This will include not only processing SCBs from main thread
into a primary, but also submitting those command buffers to the queue.

The CommandProcessor is a vk::Context so it can handle errors in the
worker thread. When the main thread submits tasks to the worker
thread it also syncs any outstanding errors from the worker.

Include asynchronousCommandProcessing feature that will control
whether the worker thread task does it's work in parallel or not. If
false, we wait for the thread to complete it's work before letting the
main thread continue.  If true, the thread can execute in parallel with
the main thread.

This is in preparation for adding another transformation for vertex
attribute aliasing.  This transformation is not merged with the existing
one, because in practice vertex attribute aliasing is rare so this
transformation would be rarely done.  This makes sure the efficiency of
the main transformer is not affected, and avoids complicating it
further.
