i965: Add support for 16-bit unorm L, A, and I textures.
While not required by any particular spec version, mplayer was asking
for L16 and hoping for actual L16 without checking. The 8 bits
allocated led to 10-bit planar video data stored in the lower 10 bits
giving only 2 bits of precision in video. While it was an amusing
effect, give them what they actually wanted instead.
