Add Soong config variable for libgbm build variants
minigbm has platform dependent compile flags that need to be set
correctly to work on the chipset (e.g. -DDRV_I915 on Intel devices). The
libminigbm_gralloc_* variants had set them, but the libgbm doesn't. This
CL introduces a Soong config variable "platform" under "minigbm"
namespace to control libgbm build variants, and apply the flags from
gralloc library to each variant.
Device .mk's can set it like:
$(call soong_config_set, minigbm, platform, intel)
Refer to

for ChromiumOS configuration of the compile flags.
