I wrote this to convert run_tests.get_backend_commands() over to the
new meson wrappers, but that turned out to be harder than I expected,
so just splitting this out for now.
This allows the NINJA environment variable to support all the Windows special
cases, especially allowing an absolute path without extension.
Based on a patch by Yonggang Luo.

This matches `meson test`, and there's really no other meaning that
could be attributed to this, since you would call `meson` to get the
version, not the `compile` sub-command.
With this running `meson compile` inside the builddir actually works,
and you don't have to do `meson compile -C .`
Clearly this was the intent since the option already has `default='.'`
