93559d5c - Add a `--platform` argument to enable resolving against a target platform (#3111)

Add a `--platform` argument to enable resolving against a target platform (#3111) ## Summary I've wanted to try this for a long time, so decided to give it a shot. The basic idea is that you can provide a target triple (e.g., `--platform x86_64-pc-windows-msvc`) and resolve against that platform, rather than the currently-running platform. It's functionally similar to `--python-version`, though a bit simpler since there's no need to engage with `Requires-Python`. Our infrastructure is well-setup for this and so, in the end, it's actually pretty straightforward: for each triple, we just need to override the markers and platform tags.
