feat(compiler-sfc): add preserveTilde option for asset URL and srcset transformations

[edison1105]

close #13460 close https://github.com/vitejs/vite-plugin-vue/issues/15

This PR introduces a new option, preserveTilde, for handling the ~ in asset URLs.

• The default value is false, which keeps the existing behavior: leading ~ and ~/ are stripped - it's exactly the same as before.
• If set to true, leading ~ and ~/ are preserved and resolution relies on the bundler (e.g., Vite).

Usage example:

  // vite.config.js
  plugins: [vue({
    template:{
      transformAssetUrls:{
        preserveTilde: true 
      }
    }
  })],

Summary by CodeRabbit

• New Features
  • Added support for preserving the tilde (~) character in asset URLs and srcset attributes when specified, improving compatibility with certain aliasing setups.
• Tests
  • Introduced new test cases to verify the behavior of asset URL and srcset transformations when the preserveTilde option is enabled.
