xtensa-build-zephyr.py: add flexibility to generate `tools/` only 

Installing most of the tools/ directory does not technically require
building any platform, so add that possibility.

This is useful because the Jenkins-based CI builds the (userspace) tools
separately. So far it has been picking hardcoded source paths but of
course the HWMv2 transition just broke that:
https://github.com/thesofproject/sof/pull/8913

While it's too late this time (we want to keep CI able to test stable
branches for some time), this commit prepares a future where all CIs can
stop hardcoding Zephyr source paths and pick the output of the
xtensa-build-zephyr.py installer and indirection layer instead.
