Allow parentheses in yield arguments for Style/MethodCallWithArgsParentheses

[gsamokovarov]

When using the omit_parentheses style, we don't recognize yield
argument calls and require parentheses omission. If we yield multiple
values, we cannot omit the parentheses in method calls as this won't be
valid Ruby. We currently register offenses for:

# Example 1
yield File.basename(path)
      ^^^^^^^^^^^^^^^^^^^ Omit parentheses for method calls with arguments.

# Correction...
yield File.basename path # 👈 This compiles.

# Example 2
yield path, File.basename(path)
            ^^^^^^^^^^^^^^^^^^^ Omit parentheses for method calls with arguments.

# Correction...
yield path, File.basename path  # 👈 This DOES NOT!!!

If we treat yield arguments as any other method call arguments, we'll
allow the parentheses and let people write valid Ruby in the cases
above.
