  [libc++] Refactor tests for aligned allocation and sized deallocation (#117915)

This patch refactors the tests around aligned allocation and sized
deallocation to avoid relying on passing the -fsized-deallocation or
-faligned-allocation flags by default. Since both of these features are
enabled by default in >= C++14 mode, it now makes sense to make that
assumption in the test suite.

A notable exception is MinGW and some older compilers, where sized
deallocation is still not enabled by default. We treat that as a "bug"
in the test suite and we work around it by explicitly adding
-fsized-deallocation, but only under those configurations.
