glsl: Use bit-flags image attributes and uint16_t for the image format
All of the GL image enums fit in 16-bits.
Also move the fields from the anonymous "image" structucture to the next
higher structure. This will enable packing the bits with the other
bitfield.
Valgrind massif results for a trimmed apitrace of dota2:
n time(i) total(B) useful-heap(B) extra-heap(B) stacks(B)
Before (32-bit): 76 40,572,916,873 68,831,248 63,328,783 5,502,465 0
After (32-bit): 70 40,577,421,777 68,487,584 62,973,695 5,513,889 0
Before (64-bit): 60 36,822,640,058 96,526,824 88,735,296 7,791,528 0
After (64-bit): 74 37,124,603,758 95,891,808 88,466,712 7,425,096 0
A real savings of 346KiB on 32-bit and 262KiB on 64-bit.
