Turbopack: Remove old macos-compress script (#90967)

@wbinnssmith added these scripts a long time ago at my suggestion/urging, but I think they ended up bad for a couple reasons that were hard to foresee at the time:

- afsctool operates in-place and doesn't atomically write the compressed file, so if the process gets interrupted, your `target` directory is corrupted. https://github.com/Dr-Emann/applesauce is better for this reason.
- This doesn't acquire the cargo lock, and modifying files while cargo is running is a good way to get corruption of the `target` directory.

https://github.com/bgw/cargo-apfs-compress is my latest attempt at solving this, though I don't have a `LaunchAgents` config for it.  
  
Regarding `node_modules`: pnpm creates reflinks from a shared global store on apfs. Trying to compress these reflinked files is just going to hurt you because it'll break the data deduplication that would've otherwise happened.

 It will also clean up other caches (pnpm store, cargo, etc.) and run `git gc` for you.

-### MacOS disk compression
-
-If you want to automatically use APFS disk compression on macOS for `node_modules/` and `target/` you can install a launch agent with:
-
-```bash
-./scripts/LaunchAgents/install-macos-agents.sh
-```
-
-Or run it manually with:
-
-```bash
-./scripts/macos-compress.sh
