…n bugs (#483)

**Summary**
Perf/cleanup:
- Remove redundant slice in getPrefixLength (return indexOf result
directly)
- Precompute allContexts in _loadTsconfigPathsMap to avoid per-call
object rebuild
- Parallelize _loadTsconfigReferences with Promise.all instead of
sequential await

Bug fixes:
- Fix baseUrl inheritance from deep extends chains: use
dirname(extendedConfigPath) (absolute) instead of
dirname(extendedConfigValue) (relative), so non-sibling directory
structures resolve correctly
- Fix scoped npm package extends (@scope/name): add fallback to resolve
node_modules/@scope/name/tsconfig.json when
node_modules/@scope/name.json is not found
microsoft/TypeScript#62753

Add test fixtures and cases covering both bug scenarios.

<!-- In addition to that please answer these questions: -->

**What kind of change does this PR introduce?**

**Did you add tests for your changes?**

Yes

**Does this PR introduce a breaking change?**

No
**If relevant, what needs to be documented once your changes are merged
or what have you already documented?**
