android: export libcamera_metadata and libsync to sysroot

The patch makes the following modifications to the build tools in order
to export android libraries to sysroot:

1. Remove source and header files which are now provided by libcamera_metadata
   or libsync.
2. Make android/ an independent build root. Originally it was a submodule
   of arc-camera/. This is to strip dependency on libchrome. The android
   libraries do not require libchrome to build.
3. Update the module.mk of hal_adapter/, usb/hal/, and camera3_test/
   accordingly so that they link to the exported libcamera_metadata and
   libsync.
