feat(prefer-template-ref): support auto-fix

[9romise]

Re-implement of #2632 (closes #2632). (I really love this feature!)
But this PR doesn't insert import { useTemplateRef } from 'vue' automatically.
Because I think that falls outside the scope of this rule. Additionally, some users rely on unplugin-auto-import and would have to remove the unnecessary import to maintain clean imports.

Please merge #2982 first.

Pull request overview

This PR implements auto-fix functionality for the prefer-use-template-ref rule, which automatically converts ref() and shallowRef() calls to useTemplateRef('name') when they are used as template refs. The implementation intentionally does not auto-import useTemplateRef to avoid conflicts with users who rely on unplugin-auto-import.

• Adds fixable: 'code' metadata to enable auto-fixing
• Implements fixer logic that correctly handles TypeScript type arguments/parameters
• Updates all test cases with expected outputs and enhanced error location information
