The switch from HIDL to AIDL does not introduce any new interface
methods.
This reverts commit 95b765d807.
Reland notes:
- Avoids using `minigbm_cros_gralloc_library_defaults`
for new `libminigbm_gralloc4_utils` to avoid having two libraries
compiling cros_gralloc_driver.cc.
- Makes `libminigbm_gralloc4_utils` a shared library.
