Aras Pranckevicius c6f5c89669 BLI: faster float<->half array conversions, use in Vulkan 
In addition to float<->half functions to convert one number (#127708), add
float_to_half_array and half_to_float_array functions:
- On x64, this uses SSE2 4-wide implementation to do the conversion
  (2x faster half->float, 4x faster float->half compared to scalar),
  - There's also an AVX2 codepath that uses CPU hardware F16C instructions
    (8-wide), to be used when/if blender codebase will start to be built
    for AVX2 (today it is not yet).
- On arm64, this uses NEON VCVT instructions to do the conversion.

Use these functions in Vulkan buffer/texture conversion code. Time taken to
convert float->half texture while viewing EXR file in image space (22M
numbers to convert): 39.7ms -> 10.1ms (would be 6.9ms if building for AVX2)
