Add SearchableAPIResource and SearchResultObject for types-stripe

[yejia-stripe]

Add type annotations for SearchableAPIResource and SearchResultObject for the stripe library stubs, and add SearchableAPIResource inheritance for relevant classes.

Fixes stripe/stripe-python#871

Are some of these things new in stripe v4? If so, you may need to bump the version field in METADATA.toml to get stubtest to pass (but that might also add some more errors to CI — see #8490)

@AlexWaygood The overall feature isn't new to v4, but the way I'm typing it is not technically accurate? The search and search_auto_paging_iter don't actually exist on SearchableAPIResult, but I didn't want to type each subclass separately. They will be defined after I release stripe/stripe-python#873, but that would be for v4.

I would like to make this change without updating to v4. Would I be able to add an exception for this for now? Or should I add types for each subclass?

Yeah that should be fine! Sorry for the delayed response!

We do that for a few other classes, e.g.:

typeshed/tests/stubtest_allowlists/py3_common.txt

Lines 101 to 102 in b4d9105

	importlib.abc.MetaPathFinder.find_spec # Not defined on the actual class, but expected to exist.
	importlib.abc.PathEntryFinder.find_spec # Not defined on the actual class, but expected to exist.

You'll just need to add some entries to https://github.com/python/typeshed/blob/master/stubs/stripe/%40tests/stubtest_allowlist.txt to get the CI happy with it :)

Mostly looks good! Just one suggestion, and two questions
