chore(issue-priority): Split up priority GA changes to use a permanent flag (#75297)

The `organizations:seer-based-priority` flag was previously used to gate
all changes related to priority GA. This change introduces a new flag,
`organizations:priority-ga-features` which gates the GA feature set that
is intended to be released to all customers.
`organizations:seer-based-priority` will be converted to a permanent
flag to control whether Seer's severity service should be involved in
the priority calculations.
