Can omit parentheses layout for patterns #6933
Description
Ruff avoids adding parentheses to expressions that start or end with a parenthesized node (see can_omit_parentheses).
This is implemented by using optional_parentheses in conjunction with the in_parentheses_only_* builders. We need something similar for patterns to support

A
| B
| ["Aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa", "bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb"]
):
