Also, define a new dri configuration option so users can disable exposure of
fp16 formats. Make fp16 opt-in for i965.

Change dri2_add_config to take arrays of shifts and sizes, and compare with
those set in the dri config. Convert all platform driver masks
to shifts and sizes.
In order to handle older drivers, where shift attributes aren't available,
we fall back to the mask attributes and compute the shifts with ffs.

The existing mask attributes can only support up to 32 bpp. Introduce
per-channel SHIFT attributes that indicate how many bits, from lsb towards
msb, the bit field is offset. A shift of -1 will indicate that there is no
bit field set for the channel.
As old loaders will still be looking for masks, we set the masks to 0 for
any formats wider than 32 bpp.

This debug option allows vkGet[Instance/Device]ProcAddr() to succeed
even if the extension associated with the requested entrypoint was not
enabled.
This has come in handy in a few instances when debugging VR
applications, so I thought it would be good to have a cleaned up version
upstreamed.

This better matches all the other atomic intrinsics such as those for
SSBOs and shared variables where the sign is part of the intrinsic
opcode. Both generators (GLSL and SPIR-V) know the sign from the type
of the image variable or handle. In SPIR-V, signed min/max are separate
opcodes from unsigned.
