Update usage flag handling for hwc

Add support for GRALLOC_USAGE_HW_COMPOSER usage flag
mapping it to GBM flags, inspired by minigbm implementation.

Fixes the artifacts issues with vulkan hal radv with the following apps
with benefit to all apps using HWC layers:
V1 - GPU Benchmark Pro (Vulkan API)
PPSSPP - PSP emulator
Sascha Willems Vulkan Examples (e.g. Vulkan Gears, Vulkan Texture)
