bors cbeda5cbeb Auto merge of #86467 - ChrisDenton:win-env-clear, r=JohnTitor 
Windows: Fix `Command::env_clear` so it works if no variables are set

Previously, it would error unless at least one new environment variable was added. The missing null presumably meant that Windows was reading random memory in that case.

See: [CreateProcessW](https://docs.microsoft.com/en-us/windows/win32/api/processthreadsapi/nf-processthreadsapi-createprocessw) (scroll down to `lpEnvironment`). Essentially the environment block is a null terminated list of null terminated strings and an empty list is `\0\0` and not `\0`.

EDIT: Oh, [CreateEnvironmentBlock](https://docs.microsoft.com/en-gb/windows/win32/api/userenv/nf-userenv-createenvironmentblock) states this much more explicitly.

Fixes #31259
