gles3: Prohibit set/get of GL_FRAMEBUFFER_SRGB.
GLES 3 supports sRGB functionality, but it does not expose the
GL_FRAMEBUFFER_SRGB enable/disable bit. Instead the implementation
is expected to behave as though that bit is always enabled.
This patch ensures that ctx->Color.sRGBEnabled (the internal variable
tracking GL_FRAMEBUFFER_SRGB) is initially true in GLES 2/3 contexts,
and that it cannot be modified through the GLES 3 API.
This is safe for GLES 2, since ctx->Color.sRGBEnabled has no effect on
non-sRGB formats, and GLES 2 doesn't support any sRGB formats.
