Removing TS compiler

[d-gubert]

What? ⛵

Removing the compilation process for the apps. From this point on, we're expecting the apps package to contain their compiled versions already.

This is just part of the project - most of the work will be done on other packages.

Rocket.Chat PR: RocketChat/Rocket.Chat#18687

Why? 🤔

By doing this we achieve:

• A smaller dependency tree for the package, since we will not require the typescript package anymore.
• A smaller memory footprint in the Rocket.Chat server, as we will not load typescript in runtime anymore.
• A smaller surface for compilation errors to happen when updating the Apps-Engine version in a running server.
• A shorter start-up time for the Rocket.Chat server, as it will not need to compile all installed apps anymore.
• A more flexible development experience, not tied to the typescript version we ship with the Apps-Engine.
