android: hal: Add Camera3 HAL
Add libcamera Android Camera HALv3 implementation.
The initial camera HAL implementation supports the LIMITED hardware
level and uses statically defined metadata and camera characteristics.
Add a build option named 'android' and adjust the build system to
selectively compile the Android camera HAL and link it against the
required Android libraries.
