Corentin Wallez bd8de5d2a4 Add MetalRenderR8RG8UnormSmallMipToTempTexture workaround
This workaround replaces the toggle that forbids creating mipmapped
R8Unorm and RG8Unorm textures on Metal. Instead it adds a Metal render
pass workaround that renders to a temporary texture under certain
conditions, then copies back to the correct mip level.

The texture lazy-clearing code is also changed to use the helper that
does workarounds for Metal render passes.

A test is added that triggers the issue with a small amount of code, but
more extensive coverage is left to the CTS. For example texture_zero
tests caught multiple issues during the creation of this CL.

Corentin Wallez 46bef8aae6 Tighten the suppression for texture_zero failures.
It is failing for a single format when trying to copy to a buffer
because the depth-specific format for depth23unorm-stencil8 buffer is
depth24plus which is not copyable.

Austin Eng 390b5a2176 Generalize expectation for recently added suppression.
intel-0x3e92 was not added, but intel-0x5912 was - leading
to flaky CQ rejection depending on what bot happened to run
the task.

Generalize this expectation since it fails on all platforms
anyway.
