mesa: Expose GL_OES_required_internalformat on GLES contexts.
This extension is effectively a backport of GLES3's internalformat handling to GLES 1/2. It guarantees that sized internalformats specified for textures and renderbuffers have at least the specified size stored. That's a pretty minimal requirement, so I think it can be dummy_true and exposed as a standard in Mesa. As a side effect, it also allows GL_RGB565 to be specified as a texture format, not just as a renderbuffer. Mesa had previously been allowing 565 textures, which angered DEQP in the absence of this extension being exposed. v2: Allow 2101010rev with sized internalformats even on GLES3, citing the extension spec. Extend extension checks for GLES2 contexts exposing with texture_float, texture_half_float, and texture_rg. v3: Fix ALPHA/LUMINANCE/LUMINANCE_ALPHA error checking (GLES3 CTS failures) v4: Mark GL_RGB10 non-color-renderable on ES, fix A/L/LA errors on GLES2 with float formats.
