[lib] Update threadHasPermission to support MinimallyEncodedRawThreadInfo

Summary:
Update threadHasPermission in thread-utils to support MinimallyEncodedRawThreadInfo via .minimallyEncoded and hasPermission check.

Going to go ahead and do a refactor of a bunch of utils in thread-utils all at once, but will separate out the more "important" ones(?) into their own diffs

Depends on D9809

Test Plan: Will write unit tests once all the Flow stuff is figured out.
