Metal: fix max varyings, copyImage between mips, depth fmt
- GLSLTest_ES3.MaxVaryingWithFeedbackAndGLline failed before because
gl_Position takes up one slot from max varyings on Metal back-end.
FIXED
- Previously, copyImage() between mips of the same texture would fail.
Due to the read RenderTargetMtl is released before the copy happens.
FIXED
- GL_DEPTH_COMPONENT24 texture data upload didn't work due to the source
32 bit depth data wasn't handled properly. FIXED
- D24S8 format will be disabled on AMD for now, it will be converted to
D32S8 instead.

Metal: Implement transform feedback
- XFB is currently emulated by writing to storage buffers.
- Metal doesn't allow vertex shader to both write to storage buffers and
to stage output (i.e clip position). So if GL_RASTERIZER_DISCARD is
NOT enabled, the draw with XFB enabled will have 2 passes:
+ First pass: vertex shader writes to XFB buffers + not write to stage
output + disable rasterizer.
+ Second pass: vertex shader writes to stage output (i.e.
[[position]]) + enable rasterizer. If GL_RASTERIZER_DISCARD is
enabled, the second pass is omitted.
+ This effectively executes the same vertex shader twice. TODO:
possible improvement is writing vertex outputs to buffer in first
pass then re-use that buffer as input for second pass which has a
passthrough vertex shader.
- If GL_RASTERIZER_DISCARD is enabled, and XFB is enabled:
+ Only first pass above will be executed, and the render pass will use
an empty 1x1 texture attachment since rasterization is not needed.
- If GL_RASTERIZER_DISCARD is enabled, but XFB is NOT enabled:
+ we still enable Metal rasterizer.
+ but vertex shader must emulate the discard by writing gl_Position =
(-3, -3, -3, 1). This effectively moves the vertex out of clip
space's visible area.
+ This is because GLSL still allows vertex shader to write to stage
output when rasterizer is disabled. However, Metal doesn't allow
that. In Metal, if rasterizer is disabled, then vertex shader must
not write to stage output.
- See src/libANGLE/renderer/metal/doc/TransformFeedback.md for more
details.

Metal: Use compute to generate 3D texture's mipmap.
- Metal's built-in blit based mipmap generator doesn't use box
filtering. Hence manual generation using compute is needed.
- Compute based mipmap gen can generate up to 4 mips per pass if the
base level is power of 2.
- This approach can be extended to 2D/cube texture's mipmap generation
in future.

Metal: Init format table using Metal-Feature-Set-Tables.pdf
- Format table is now initialized using informations from
https://developer.apple.com/metal/Metal-Feature-Set-Tables.pdf.
Previously, it was setup using gl::GenerateMinimumTextureCaps().
- This CL also adds InitializeTextureDataFunction and LoadFunctionMap to
mtl::Format. They are needed to properly initialize/convert textures
with non-normalized formats.
- This CL is prerequisite for integer & floating point format supports.
- New test: DXT1CompressedTextureTest.DXT1Alpha (this test was added
in the past but was reverted for some reasons).

With this extension, it is possible to import Vulkan images into ANGLE
(similar to EXT_external_objects) while specifying the Vulkan create and
usage flags used to create that image. This can be used by the
application to drop usage flags it does not need to improve performance,
or add create flags as it requires.

Metal: deferred render command encoder creation.
MTLRenderCommandEncoder creation will be deferred until a render pass
ends.
Commands will be stored into a back-end owned buffer during render pass.
At the end of the render pass, those commands will be re-encoded into an
actual MTLRenderCommandEncoder.
Benefits:
- Useful for future implementation of occlusion query buffer where it
could be allocated right before the end of a render pass to be big
enough to store all queries within the render pass.
- It's possible to change load option (deferred clear) as long as there
is no draw call issued yet. This is not implemented yet.
- Possibility of commands' re-ordering.

Vulkan: Make texture syncState aware of upcoming generateMipmap
By letting TextureVk::syncState know it's being called for
generateMipmap, it can make a better decision to initialize the image:
- Staged updates to mips that are going to be overwritten are dropped
- The image is created with full mipchain to avoid a redefine in the
following generateMipmap() call.
