python3: support profile optimized build
Make it possible to do profile-optimized build. The implementation is
virtually identical to how we do it in Python 2.7. Basically, you need
to define PYTHON3_PROFILE_OPT = "1" in your local.conf and have profile
data available in the location pointed to by PYTHON3_PROFILE_DIR.
Profile data can be obtainen e.g. by running bitbake python-pgo-image -c
profile3.
