Support for TSGo in IDE

[ryanylee]

Describe the problem

Currently TSGo does not support rootDirs which is required for sveltekit's unique auto generated type files. There's potential talk of deprecating rootDirs entirely in future TS6 microsoft/TypeScript#61885.

Obviously supporting TSGo would require big changes to svelte-check, but it'd be nice to somehow have a way to run the experimental version of TSGo in one's IDE. It seems to work fine in .svelte files, it's just any .server.ts that causes issues.

Describe the proposed solution

This seems like it'll sort of be solved in the long term with remote functions but just throwing it on the team's radar in case Typescript does in fact remove rootDirs

For the editor side, it's tracked in sveltejs/language-tools#2733. For now, Svelte files can't use tsgo, and the zero-configure type safety won't work in the TS/JS file either. I think we can leave this open to track the rootDirs issue in SvelteKit, but for the editor side, it's sveltejs/language-tools#2733
