bitbake: bitbake-setup: add 'install-buildtools' command

This basically calls install-buildtools from oe-core/poky, but
it ensures via command line parameters that the installation
location is stable and the downloads are preserved for reproducibility:

$ bin/bitbake-setup install-buildtools
Loading settings from /home/alex/bitbake-builds/bitbake-setup.conf

======
Buildtools archive is downloaded into /home/alex/bitbake-builds/yocto-master-testing/buildtools-downloads/20250319141333 and its content installed into /home/alex/bitbake-builds/yocto-master-testing/buildtools

... (output from install-buildtools script)
======

It also detects when buildtools are already installed, and will direct
users what to do:
======
alex@Zen2:/srv/work/alex/bitbake$ bin/bitbake-setup install-buildtools
Loading settings from /home/alex/bitbake-builds/bitbake-setup.conf

Buildtools are already installed in /home/alex/bitbake-builds/yocto-master-testing/buildtools.
If you wish to use them, you need to source the the environment setup script e.g.
$ . /home/alex/bitbake-builds/yocto-master-testing/buildtools/environment-setup-x86_64-pokysdk-linux
You can also re-run bitbake-setup install-buildtools with --force option to force a reinstallation
