Repro Code

`${"\u00E5"}`;
// autofixes to 
// "\u00E5";

` ${"\u00E5"} `;
// autofixes to 
// ` å `;

ESLint Config

module.exports = {
  "rules": {
    "@typescript-eslint/no-useless-template-literals": "error",
    "no-useless-escape": "error"
  }
}

tsconfig

{
  "compilerOptions": {
    // ...
  }
}

Expected Result

I expect that the autofixed strings should preserve the string type and the escaped characters as the author wrote them.
So, we should have

`${"\u00E5"}`;
// autofixes to 
// `\u00E5`;

` ${"\u00E5"} `;
// autofixes to 
// ` \u00E5 `;

Actual Result

actual autofix results change user's input regarding template and and escaped characters.

Additional Info

This can also result in multiline template literals instead of single line literals that include a \n.

It doesn't impact correctness at runtime, but it isn't the purview of this rule to make these stylistic changes (with the caveat, of course, that obviously $s and backticks still need to be escaped in order to incorporate a string literal into a template string)
