Description (last modified by Adam Johnson)

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.

I found this property was taking ~15 of the total runtime for system checks on a project with 118 models. calls. Turning it into a cached_property and adding a no-translation fast path saves nearly all this cost, with the below results.

Before: 520 calls taking 10ms
After: 105 calls taking ~0ms
