## Message

````
Replace `unreachable` with error return for non-standard Windows targets

This new error mirrors the error returned from the Elf struct (error.UnsupportedElfArchitecture):

https://github.com/ziglang/zig/blob/0adcfd60f4fcfd01c74a6477cbcef187ce06f533/src/link/Lld.zig#L112

Before:

```
$ zig build-exe -target riscv64-windows-gnu main.zig
thread 543087 panic: reached unreachable code
```

After:

```
$ zig build-exe -target riscv64-windows-gnu main.zig
error: unable to create compilation: UnsupportedCoffArchitecture
```

Closes #24287
