meta: Add a state flag for the GL_DITHER
The Meta implementation of glClearTexSubImage is going to want to ensure tha
dithering is disabled so that it can get a consistent color across the whole
texture when clearing. This adds a state flag to easily save it and set it t
the default value when performing meta operations.

2. ./GTF -width=64 -height=64 -run=GL3Tests/packed_pixels/packed_pixels_pbo.test
In the updated gles3 conformance tests, the issue could be reproduced.
./glcts --deqp-case=ES3-CTS.gtf.GL3Tests.packed_pixels.packed_pixels_pbo --deqp-surface-width=64 --deqp-surface-height=64 --deqp-base-seed=1 --deqp-surface-type=window --deqp-gl-config-id=14
I'm able to reproduce on bdw, and confirmed the bisect.
Patch sent for review, it may require little discussion and revision.
I've pushed this patch which I think should fix it. I don't have access to a BDW machine to test it though.
