Auto merge of #125579 - Noratrieb:print-host, r=davidtwco
Add `--print host-tuple` to print host target tuple

People often parse `-vV` output to get to the host tuple, which is annoying to do. It's easier to just get it directly.

I called it "host-tuple" instead of "host" because it's clearer that it's just the target name. I'm open to different names, but I think this one is fine.

a quick GitHub search for `'^host` reveals many instances of people doing the parsing, for example:

needs a compiler FCP. I could also do an MCP but I think just an FCP here makes the most sense.
