[roll] Roll fuchsia [sestarnix] Simplify the PermissionCheck API surface

Reduce the has_permissions() API to simply has_permission(), since
multi-permission checks are vanishingly rare and can be optimized
for within the AVC. Single-permission checks make audit logging a
little simpler.

Also remove support for the PermissionCheck trait with QueryMut,
since that is not used anywhere and mutability of cache structures
can be hidden behind an immutable temporary interface.
