android: Introduce the Android buffer info abstraction

Roman Stratiienko requested to merge roman.stratiienko/mesa:common-android-buffer-layer into main

Both EGL and Vulkan implementations require obtaining buffer metadata, e.g., format, modifier, offsets, strides, etc.

Currently, mesa3d doesn't have a generic solution, and every Vulkan implementation uses its getters. Most of the getters rely on kernel metadata storage that is available for x86-based GPU drivers.

ARM-based Vulkan drivers rely on userspace metadata sharing, making it important to use advanced metadata API. Otherwise, the driver will work with limited functionality (no YUV, lack of support for modifiers, etc.)

Current EGL buffer getter implementation is advanced enough and used as a base for a common Android buffer-getter logic.
