2114 extensibility manage serverless execution from built code (#17317)

Summary

- Serverless functions are now built when created/updated instead of at
execution time
  - Added builtHandlerPath field to track pre-built function artifacts
- Renamed base-typescript-project to seed-project with pre-built ESM
output included
- Renamed file folder enums for consistency (Functions → BuiltFunction,
SourceCode → Source)
  - supports backwards compatibility with existing serverless functions

Tested with all combinations
- storage : local driver and S3 driver
- serverless : local driver and lambda driver
