graphics: make mapper default impl a header library
Reimplement the default impl as a header-only library,
android.hardware.graphics.mapper@2.0-passthrough, based on the HAL
support library.
Effectively, this renames Gralloc[01]Mapper to Gralloc[01]Hal, and
make adjustments here and there to meet the requirements of the HAL
support library. This also adds GrallocLoader to load either of
Gralloc[01]Hal and create an IMapper instance.
libgrallocmapperincludes is renamed to follow the new naming and
include path conventions.
Test: boots and VTS
