Fix unnecessary one-time recompile of stdlib with -enable-ossa-flag (#39516)

* Fix unnecessary one-time recompile of stdlib with -enable-ossa-flag

This includes a bit in the module format to represent if the module was
compiled with -enable-ossa-modules flag. When compiling a client module
with -enable-ossa-modules flag, all dependent modules are checked for this bit,
if not on, recompilation is triggered with -enable-ossa-modules.

* Updated tests
