Switch monaco to off of moduleResolution: classic

Browse Source 
Fixes #270408

Trying to move some of the monaco related checks/tconfigs off of `moduleResolution: classic`. This legacy config is causing a lot of pain while trying to update the trusted-types typings, which is itself blocking picking up the latest dompurify

I initially tried a more scoped change but just could not get it working. So instead I ended up trying to rework our `LanguageServiceHost` to be more standard
