build/fs: modernize file-system helpers

Browse source 
Replaced custom recursive directory creation and deprecated `fs.rmdirSync` logic with the native APIs introduced in Node ≥10:

* [ensureDir](cci:1://file:///c:/Users/T2430514/Downloads/monaco-editor/build/fs.ts:12:0-21:1) now calls `fs.mkdirSync(dirname, { recursive: true })`
  – creates full path atomically
  – avoids race conditions and extra loops

* [removeDir](cci:1://file:///c:/Users/T2430514/Downloads/monaco-editor/build/fs.ts:44:0-79:1) now ends with `fs.rmSync(dirPath, { recursive: true, force: true })`
  – officially supported replacement for `fs.rmdirSync`
  – handles non-empty directories and future Node versions

This simplifies the code, removes deprecation warnings on Node 16+, and prevents build/packaging scripts from failing on newer runtimes.
