ProcessBuilder Allow Use of `raw_arg` for `Command` on specific platforms

[jonatino]

Problem

rust-lang/rust#29494
rust-lang/rust#92939

Right now when using ProcessBuilder::exec_with_streaming, it uses the cmd.arg() method to build the Command which on Windows, does not allow us to pass in args that are in quotes (see the above issues for more information).

Steps

No response

Possible Solution(s)

It'd be nice if we could specify if an arg is "raw" or not, or have some other work around.

Notes

I'm using the cargo-quad-apk crate which uses cargo-util for executing a build command. The problem is, if your project has spaces in the name on windows, the Clink-args escape incorrectly and cause the tool to fail to resolve paths.
