PermissionBackend: support bulk evaluation of UiAction

Support a PermissionBackend to consider all actions on a single REST
API resource in one pass by aggregating PermissionBackendConditions
and passing them through bulkEvaluateTest.

An implementation should use PermissionBackendCondition.set(boolean)
to cache any decision from testOrFalse, allowing the final isVisible
and isEnabled evaluations to bypass calling testOrFalse dynamically.
