support pnp resolver

[gun-yu]

This PR adds support for PnP resolution.

#1875 in the previous discussion, I have internalized pnp-go into the repository.

Please note that the PR has become quite large due to the inclusion of the PnP source and test code. I apologize for the length and appreciate your understanding.

what is pnp

Yarn Plug’n’Play (PnP) is a dependency resolution system that removes the need for a traditional node_modules folder.
describe at #460

how to support

add pnp resolution config in host

type host struct {
	orchestrator *Orchestrator
	host         compiler.CompilerHost
	// Caches that last only for build cycle and then cleared out
	extendedConfigCache tsc.ExtendedConfigCache
	sourceFiles         parseCache[ast.SourceFileParseOptions, *ast.SourceFile]
	configTimes         collections.SyncMap[tspath.Path, time.Duration]

	// caches that stay as long as they are needed
	resolvedReferences parseCache[tspath.Path, *tsoptions.ParsedCommandLine]
	mTimes             *collections.SyncMap[tspath.Path, time.Time]
	resolvedReferences  parseCache[tspath.Path, *tsoptions.ParsedCommandLine]
	mTimes              *collections.SyncMap[tspath.Path, time.Time]
	pnpResolutionConfig *pnp.ResolutionConfig
}

add pnp branch in resolver.go

// resolveTypeReferenceDirective
// skip typeRoots because PnP knows exactly where each @types is located.
	if r.resolver.pnpResolutionConfig != nil {
		if resolvedFromNearestNodeModulesDirectory := r.loadModuleFromNearestNodeModulesDirectory(true /*typesScopeOnly*/); !resolvedFromNearestNodeModulesDirectory.shouldContinueSearching() {
			return r.createResolvedTypeReferenceDirective(resolvedFromNearestNodeModulesDirectory, true /*primary*/)
		}
	} else {
		if len(typeRoots) > 0 {
			if r.tracer != nil {
				r.tracer.write(diagnostics.Resolving_with_primary_search_path_0.Format(strings.Join(typeRoots, ", ")))
			}

// loadModuleFromNearestNodeModulesDirectory
if r.resolver.pnpResolutionConfig != nil {
			if result := r.loadModuleFromPNP(priorityExtensions, typesScopeOnly); !result.shouldContinueSearching() {
				return result
			}
		} else {
			if result := r.loadModuleFromNearestNodeModulesDirectoryWorker(priorityExtensions, mode, typesScopeOnly); !result.shouldContinueSearching() {
				return result
			}
		}

todo: add pnp support later

I change this function's interface

These test cases were taken from pnp-rs, but since they are relatively complex to run and maintain.
I think it would be fine to remove them if they’re not considered necessary.
Please let me know your thoughts!

@microsoft-github-policy-service agree

On second thought, this way I wouldn’t be able to take advantage of the cached VFS, so I’m thinking of moving its location instead.
