gh-89554: Document standard type objects in types as classes (GH-150676)

Use the directive and the role "class" instead of "data" for classes
exposed in the types module.

(cherry picked from commit bc05544)

Backport to 3.13 omits the parts that do not apply on this branch: the Doc/whatsnew/3.15.rst changes, and the FrameLocalsProxyType / LazyImportType entries in types.rst (both 3.15-only). The remaining .. data:: -> .. class:: conversions and the howto/whatsnew cross-reference updates are applied.
