feat(cli-utils): add experimental support for `.svelte` files

Summary

This abstracts our usage of volar’s utilities down to VirtualCode wrappers and abstracts it to have parity with the Svelte file support. The Svelte2TSX compiler has been added to compile Svelte files to TSX as well.

Notably, this changes the approach slightly. To risk confusing external files with virtual files, we now create a SourceFile of the project file (svelte/vue file) outside of our TypeScript program and don't add it to the project.

Redirections to the virtual file and such still function as before. But the biggest change is that all commands will now iterate over the virtual files (e.g. .vue.ts and .vue.svelte) instead of the non-TS project files (.vue and .svelte), since those aren't loaded into TypeScript anymore. The output of the logger is hence mapped and getFilePosition now uses the position mapper as needed.

Set of changes

Squash usage of Volar helpers down to just VirtualCode
Add async-imports for external virtual code creators
Add file location mapper
- This will either map from project -> virtual or virtual -> project file, so it can be used for both, the GraphQLSP plugin info methods, and the logger outputs
Add svelte example
