Message : Re-land: Don't expose non-conformant multisampling modes on GL Re-landing with a fallback for failed internal format queries to work around issue seen on Shield TV. Also fixed wrong handling of integer RG formats in isRequiredRenderbufferFormat. Some NVIDIA GL drivers expose non-conformant multisampling modes. The conformance of multisampling modes can be queried using the extension NV_internalformat_sample_query. Use it to filter out the non-conformant modes from the modes that are exposed by ANGLE. The MAX_SAMPLES value and other similar values stored in caps also need to be lowered to match the maximum number of samples exposed for required formats. There seems to be an NVIDIA driver bug related to querying STENCIL_INDEX8 multisample format. Work around this by querying DEPTH24_STENCIL8 instead. There's also some confusion around whether RGB9_E5 should be renderable. Once the floating point texture extensions got rolled into the core GL spec, it was eventually made clear that RGB9_E5 is intended not to be renderable. The extension specs that predate float textures in the core spec do suggest that it would be renderable, but in practice drivers that advertise the extension strings don't reliably implement RGB9_E5 as renderable. Solve this by disabling it as a renderable format and adding an explanatory comment.
