Fix cases where memory allocation was done with g_new / g_malloc but the data was not freed with g_free. This will work fine in normal usage but could cause GLib memory debugging to not work correctly.

It looks like this pull request may not have tests. Please make sure to add tests or get an explicit test exemption before merging.

If you are not sure if you need tests, consider this rule of thumb: the purpose of a test is to make sure someone doesn't accidentally revert the fix. Ask yourself, is there anything in your PR that you feel it is important we not accidentally revert back to how it was before your fix?

Reviewers: Read the Tree Hygiene page and make sure this patch meets those guidelines before LGTMing. If you believe this PR qualifies for a test exemption, contact "@test-exemption-reviewer" in the #hackers channel in Discord (don't just cc them here, they won't see it!). The test exemption team is a small volunteer group, so all reviewers should feel empowered to ask for tests, without delegating that responsibility entirely to the test exemption group.

Code Review

This pull request updates memory deallocation in fl_engine.cc and fl_mock_binary_messenger.cc by replacing free with g_free. Feedback suggests that the free_locale function should also deallocate the script_code and variant_code members of the FlutterLocale struct to prevent memory leaks.
