Build a single GSI for O-MR1-VENDOR and Master-VENDOR

The objective of this commit is to support these 3 combinations:

1. Master-GSI + Master-VENDOR (w/ BOARD_VNDK_VERSION)
2. Master-GSI + Master-VENDOR (w/o BOARD_VNDK_VERSION for upgrading devices)
3. Master-GSI + O-MR1-VENDOR (w/ BOARD_VNDK_VERSION)

This commit defines a new property `ro.vndk.lite` to indicate the status
of BOARD_VNDK_VERSION run-time enforcement.  Now, all devices should
have `ro.vndk.version` so that `libhidlbase.so`, `libRSCpuRef.so`, and
`libnativeloader.so` can find the versioned VNDK directory.
