Skip test_freeze_simple_script() of test_tools.test_freeze if Python
is built with "./configure --enable-optimizations", which means with
Profile Guided Optimization (PGO): it just makes the test too slow.
The freeze tool is tested by many other CIs with other (faster)
compiler flags.
test.pythoninfo now gets also get_build_info() of
test.libregrtests.utils.
The test_peg_generator and test_tools.test_freeze tests now require
the 'cpu' resource. Skip these tests unless the 'cpu' resource is
enabled (it is disabled by default).
These tests are no longer skipped if Python is built with ASAN or
MSAN sanitizer.
The "freeze" tool has been part of the repo for a long time. However, it hasn't had any tests in the test suite to guard against regressions. We add such a test here. This is especially important as there has been a lot of change recently related to frozen modules, with more to come.
Note that as part of the test we build Python out-of-tree and install it in a temp dir.
