Rollup merge of #130554 - ShE3py:unsupported-exitcode, r=Noratrieb

Browse Source 
`pal::unsupported::process::ExitCode`: use an `u8` instead of a `bool`

`ExitCode` should “represents the status code the current process can return to its parent under normal termination”, but is currently represented as a `bool` on unsupported platforms, making the `impl From<u8> for ExitCode` lossy.

Fixes #130532.

History: [IRLO thread](https://internals.rust-lang.org/t/mini-pre-rfc-redesigning-process-exitstatus/5426) (`ExitCode` as a `main` return), #48618 (initial impl), #93445 (`From<u8>` impl).
