Add a fatal error.

We use this system, instead of `message(FATAL_ERROR)`,
since cmake prints a lot of nonsense if the toolchain errors out before it's found the build tools.

This `Z_VCPKG_HAS_FATAL_ERROR` must be checked before any filesystem operations are done,
since otherwise you might be doing something with bad variables set up.

#[===[.md:
# z_vcpkg_function_arguments

Get a list of the arguments which were passed in.
Unlike `ARGV`, which is simply the arguments joined with `;`,
so that `(A B)` is not distinguishable from `("A;B")`,
this macro gives `"A;B"` for the first argument list,
and `"A\;B"` for the second.

```cmake
z_vcpkg_function_arguments(<out-var> [<N>])
```

`z_vcpkg_function_arguments` gets the arguments between `ARGV<N>` and the last argument.
`<N>` defaults to `0`, so that all arguments are taken.

## Example:
```cmake
function(foo_replacement)
    z_vcpkg_function_arguments(ARGS)
    foo(${ARGS})
    ...
endfunction()
```
