Gus Caplan 5e7946fe79 vm: refactor SourceTextModule
- Removes redundant `instantiate` method
- Refactors `link` to match the spec linking steps more accurately
- Removes URL validation from SourceTextModule specifiers
- DRYs some dynamic import logic

Closes: https://github.com/nodejs/node/issues/29030
