fix: use strip-literal to strip string lterals

[antfu]

Description

Continues #7650

Using regex is impossible to handle this correctly. For example

let a = ['`', "`", `'`, `"`]

While #7650 introduced a lexer for string templates, it does not cover well with mixing quotes.

I made https://github.com/antfu/strip-literal using acron's tokenizer to handle this correctly with the minimal overhead as possible. This also unblockers #7537
