python3: split python target configuration into own class
Setting _PYTHON_SYSCONFIGDATA_NAME in python3native class globally was problematic as it was leaking into host python environment, which was causing tracebacks depending on host distro and action (typically anything involving importing sysconfig module). The new class sets the variable only in specific tasks where it is needed, and should be inherited explicitly: - use python3native to run scripts with native python - use python3targetconfig to run scripts with native python if those scripts need to access target config data (such as correct installation directories). This also adds a dependency on target python, so should be used carefully to avoid lengthening builds.
