gh-90108: Disable LTO on _freeze_module and _testembed (#109581) 

LTO optimization is nice to make Python faster, but _freeze_module
and _testembed performance is not important. Using LTO to build these
two programs make a whole Python build way slower, especially
combined with a sanitizer (like ASAN).
