Reland of gpu: Clarify sized texture format is available (https://codereview.chromium.org/2117183006)
Reason for revert:
r425684 causes blank video of mediaStream playback in MacOSX, because MacOSX
relies on the hack, which the CL removed. This CL remains the hack only in MacOSX.

> > This clarification makes it possible that gles2 decoder tracks true internal format of immutable texture. So this CL removes internal_format hack in GLES2DecoderImpl::TexStorageImpl()

> > In addition, it makes CMAA skip redundant copy path because CMAA can know true internal format.
