[ruff] Extend FA102 with listed PEP 585-compatible APIs (#20659)
Resolves https://github.com/astral-sh/ruff/issues/20512

This PR expands FA102’s preview coverage to flag every
PEP 585-compatible API that breaks without from `from __future__ import
annotations`, including `collections.abc`. The rule now treats asyncio
futures, pathlib-style queues, weakref containers, shelve proxies, and
the full `collections.abc` family as generics once preview mode is
enabled.

Stable behavior is unchanged; the broader matching runs behind
`is_future_required_preview_generics_enabled`, letting us vet the new
diagnostics before marking them as stable.

I've also added a snapshot test that covers all of the newly supported
types.
