fix: generalize multi action button (#6294)

This PR moves the CR specific logic out of the MultiActionButton and
generalises so that we can re-use it across the application. The CR
specific logic is moved into:

* ApplyButton.tsx
* ReviewButton.tsx

This fixes a bug where multi action button would be disabled if you
tried to apply an approved change request that you had created yourself.
