[OE-core] [PATCH v5 01/10] python3-native: support profile optimized build

[Markus Lehtonen]

Make it possible to build python3-native with profile directed optimization
enabled. The feature is enabled by specifying
PYTHON3_NATIVE_PROFILE_OPT = "1" in local.conf.

The profile task to be run may be specified with PYTHON3_NATIVE_PROFILE_TASK
variable in local.conf, e.g.
PYTHON3_NATIVE_PROFILE_TASK = "${S}/Tools/pybench/pybench.py -n 2 --with-gc --with-syscheck"

[YOCTO #9338]
