ENH: Expose NoDefault in pandas.api.extensions

[snitish]

• closes BUG: no type provided for pandas.api.extensions.no_default #60488
• Tests added and passed if fixing a bug or adding a new feature
• All code checks passed.
• Added type annotations to new arguments/methods/functions.
• Added an entry in the latest doc/source/whatsnew/v3.0.0.rst file if fixing a bug or adding a new feature.

From the original issue -

No type is provided for the pandas.api.extensions.no_default sentinel.

This is a problem when trying to type annotate functions or methods that forward arguments into Pandas functions that accept the no_default sentinel.
