Update VSIX release process to build TypeScript component on each native platform instead of all from the same host

Currently, cpptools' TypeScript component does not have any platform-dependent dependencies. The Release pipeline for the cpptools VSIX builds the TypeScript component for each platform from the same (Windows) host. That prevents us from introducing any platform-dependent dependencies, as they would be built for Windows and not the actual target platform.

This is preventing us from using the following dependencies, requiring us to work around these needs with non-ideal solutions:

• wordexp (requiring us to deploy our own cpptools-wordexp utility)
• node-pty (requiring us to add arguments to gcc and clang build tasks to force output colorization)

This issue is tracking updating our Release pipeline to build the TypeScript component separately on each target platform.

I believe this is blocked until Azure DevOps can provide ARM64 Mac support (or we can get an ARM64 Mac added back into our pool).

Das Issue nennt die cpptools VSIX Release-Pipeline, aber keine Dateien oder Tests; beginne damit, diese Pipeline zu finden und ihre Agents für die Zielplattformen zu überprüfen. Erledigt ist die Aufgabe, wenn die TypeScript-Komponente auf jeder Zielplattform separat erstellt wird, einschließlich der ARM64-Mac-Unterstützung oder eines verfügbaren Ersatz-Agents.
