Fix hang on Linux Intel when allocating large textures.
Intel Linux graphics drivers before kernel 5.0 can hang when allocating
large textures. Limit the texture size as a workaround.

GL: Work around Intel driver bug when clearing to zeros or ones.
When clearing to zeros or ones on some Intel drivers on Mac, the clear color
would be incorrect.
This replicates the chromium clear_to_zero_or_one_broken workaround.

Reset the base level of textures before call glTexImage on Mac
to prevent driver bugs that cause texture corruption.

GL: Clamp uniform array access on Android and AMD devices.
Chrome used to clamp it everywhere but in practice it is only needed on
these devices.

GL/D3D: Use texture uploads instead of clearing for robust init.
Chrome uses regular texture uploads on all platforms except OpenGL on
Mac to do robust resource init for textures because multiple bugs have
been observed with texture corruption.

Limit max texture size and max MSAA samples on Android.
Android devices will often fail to allocate textures this large and it is
prefereable to return an error from ANGLE instead of losing the context
due to an out of memory error.
This mirrors the limits Chrome applies with the max_texture_size_limit_4096
and max_msaa_sample_count_4 workarounds that are broadly applied to Android.
