Revert of gpu: Clarify sized texture format is available only if ES3 context or immutable texture is supported (patchset #7 id:160001 of https://codereview.chromium.org/2117183006/ )
Reason for revert:
Broke playing back recorded data as detailed
in https://crbug.com/657532. The bug has
step-by-step notes on how to repro (see also #4
in there).
Locally reverting of this CL restores the functionality.
Original issue's description:
> gpu: Clarify the sized texture format is available only if ES3 context or immutable texture is supported.
>
> 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.
