feat: added workspace member filter for actor fields (#16628)

Closes #16619

This PR adds support for filtering ACTOR fields by `Workspace Member`
subfield, enabling users to filter records by who created them with a
`Me` option.

I replicated the same UX and code structure as the Relation field filter
for consistency.

Each filter selection triggers a server-side GraphQL call. But there is
client-side filtering in `isRecordMatchingFilter.ts` which instantly
filters already-loaded records while the server is fetching new results.
I replicated this behaviour from how `FULL_NAME` and other composite
fields handle filtering.


UX decision that were taken by me (Let me know if changes are needed) : 
- The filter shows comma separated selected workspace member names until
3 members are selected. After that it shows [no of selected members]
workspace members.
