feat: codesign for deno compile binaries (#24604)

Uses [sui](https://github.com/littledivy/sui) to inject metadata as a
custom section in the denort binary.

Metadata is stored as a Mach-O segment on macOS and PE `RT_RCDATA`
resource on Windows.

Fixes #11154 
Fixes https://github.com/denoland/deno/issues/17753

```cpp
deno compile app.tsx

# on macOS
codesign --sign - ./app

# on Windows
signtool sign /fd SHA256 .\app.exe
```
