lib/oe/utils.py: add get_host_compiler_version()
Add helper function to get the host compiler and version.
Do not assume compiler is gcc.
NOTE: cannot set env to d.getVar("PATH") as that does not contain
the session PATH which was set by environment-setup-... which
breaks the install-buildtools use-case
