[BREAKING_CHANGE] Deprecate remaining entities standardId (#17639)

# Introduction
Following https://github.com/twentyhq/twenty/pull/17632 and
https://github.com/twentyhq/twenty/pull/17572
This PR deprecates the agent, skill, field metadata and role
`standardId` in favor of the `universalIdentifier` usage

## Note
- Removed previous standard ids declaration modules
- Twenty-sdk now re-exports the `STANDARD_OBJECTS` universalIdentifier
hashmap constant
- deleted some sync-metadata deadcode too ( mainly types )
