Description
Another candidate for caching, like #35230, following the same system check profiling.
The Model._meta.verbose_name_raw property returns the stringified version of the verbose_name attribute whilst temporarily disabling translations. It is only used in django.contrib.auth for creating permission names.
Profiling the system checks on a project with 118 models revealed this property was taking ~15% of the total runtime, taking 10ms across 420 calls. Turning it into a cached_property and adding a no-translation fast path saves nearly all this cost, making it take <1ms across 105 calls.
