[pyupgrade] Unwrap unary expressions correctly (UP018)

[InSyncWithFoo]

Summary

Resolves #15859.

The rule now adds parentheses if the original call wraps an unary expression and is:

• The left-hand side of a binary expression where the operator is **.
• The caller of a call expression.
• The subscripted of a subscript expression.
• The object of an attribute access.

The fix will also be marked as unsafe if there are any comments in its range.

Test Plan

cargo nextest run and cargo insta test.

Another case to consider is await int(-1).
