Accept GL_RGB/GL_RGBA for glGetInternalformativ.

The spec mentions them as color-renderable, but our IsColorRenderable() function only handles sized internal format, and adding them there might hide bugs in our renderbuffer implementation since they can only be constructed using sized internal formats. dEQP also has a note about this inconsistency, and consequently these formats are not part of the 'mustpass' set for dEQP-GLES3.functional.state_query.internal_format. So it might be a spec oversight.
