fix(linter/eslint/prefer-exponentiation-operator): preserve autofix precedence (#27150)

Fixes #27149

The safe fixer previously changed `Math.pow(a, b).toFixed(2)` to `a ** b.toFixed(2)`, changing which value receives the method call. Parenthesize the replacement when the call is used as a member object, callee, tagged template tag, TypeScript non-null operand, or TypeScript instantiation operand. Regression cases cover the reported forms and contexts where parentheses are unnecessary.
