Run vintf finalization if the target configuration does not set
RELEASE_BOARD_API_LEVEL_FROZEN to 'true'; and FINAL_BOARD_API_LEVEL
which is the version to finalize is the same with the
RELEASE_BOARD_API_LEVEL which is the version that the current tree is
building.
Also define build-step-0-and-m.sh that runs a test build after the
vintf finalization process.
