Allow analyzing Vue files in node_modules

[tiagoroldao]

• Include ".vue" files in projectFiles (using ScriptKind.Deferred)
• Use project files to determine virtual file interpolation (instead of checking for node_modules in path)

Fixes #1127

Good work. Thank you and sorry for my late response.

Is there a specific reason you are making the ScriptKind.Deferred change?
I tested and there I didn't see any problem, so I'm ok for merging it.

@octref the config returned by getParsedConfig was not returning any vue filepaths, due to scriptKind not being set as Deferred (on commandLineParser.ts, which calls getSupportedExtensions)

This was masked by the fact that the extension checked for files itself (manually ignoring node_modules)

@octref on a separate note, it may make sense to set this to an even more permissive:
PS an even more permissive setting would be:

export function isVirtualVueFile(path: string, projectFiles: Set<string>) {
  return path.endsWith('.vue.ts') && 
    (!path.includes('node_modules') || projectFiles.has(path.slice(0, -'.ts'.length)));

@tiagoroldao Do you mind sending another PR that documents this inline?

PS an even more permissive setting would be:

👍 , would be great if you can combine the changes into one PR. Being a bit looser is better, as many users don't propoerly setup jsconfig/tsconfig, so some Vue files might not be included in the TS project.

[tiagoroldao]

Will do.

@tiagoroldao I added your suggestion directly since I need to make a new release, and I want to get the isVirtualVueFile change in.

Eheh, I was busy making the PR, only saw this now! Feel free to close #2112 if it is now irrelevant!
