Serverless function follow up (#9924)

- remove asynchronous serverless function build
- build serverless function synchronously instead on activate workflow
or execute
- add a loader on workflow code step test tab test button
- add a new `ServerlessFunctionSyncStatus` `BUILDING`
- add a new route to build a serverless function draft version 
- delay artificially execution to avoid UI flashing
