Set up framework and service for Nearby module.

Files under framework/api are updated using
`build/soong/scripts/gen-java-current-api-files.sh
"packages/modules/Nearby/framework/api"  system- module-lib- && m
update-api`. They are essentially empty as nearby platform APIs do not
exist yet.

Test: mmm -j packages/modules/Nearby
