Remove unnecessary entry_points wrapper for Python 3.10+

Since the project requires Python 3.10+, we no longer need a custom
wrapper around importlib.metadata.entry_points(). In Python 3.10+,
entry_points() natively supports the group= and name= parameters and
returns EntryPoints directly.

Changes:
- Remove the entry_points() wrapper function from _entrypoints.py
- Directly import and re-export entry_points from importlib.metadata
- Update _discover.py to import EntryPoint type directly
- Simplify type annotations by removing im.EntryPoint indirection

All tests pass (296 passed, 5 skipped, 1 xfailed)
