New Lint: Implement unnecessary_paren_in_negated_if lint

[DeepakSilaych]

changelog: [unnecessary_paren_in_negated_if]: Add new lint to check for unnecessary parentheses in negated if conditions

This PR adds a new lint that detects unnecessary parentheses in negated if conditions like if !(condition) and suggests the cleaner if !condition form. This improves code readability by reducing visual noise in conditional expressions.

The implementation:

• Detects negated if conditions using pattern matching
• Identifies parenthesized expressions by examining the source snippet
• Provides a machine-applicable suggestion for removing the parentheses

fixes #14439
