Move AlertInfo's button types out of the generic type

Browse Source 
With Swift 6.4, the default value for AlertInfo.primaryButton warned that
T's Hashable conformance may be isolated and can't be used in a main
actor-isolated context. The nested AlertButton/AlertTextField types
don't depend on T, so move them to top level as AlertInfoButton and
AlertInfoTextField, and keep typealiases so existing call sites compile.

Constraining T to SendableMetatype isn't possible as the synthesized
Hashable conformances of our main actor-isolated alert enums are isolated.
