[vulkan] Add AHB support functions
bug: 122080810
This CL adds support functions for use with AHardwareBuffer
for getting buffer info and
acquiring/importing/creating buffers.
This is inspired by / based on Intel ANV
https://github.com/mesa3d/mesa/blob/master/src/intel/vulkan/anv_android.c
which has a similar layering between implementation-specific Vulkan
and AHardwareBuffer.
No new entry points are exposed yet.
Test: Builds
