  [libc++] Safe allocator tests

This revision adds:
- New test allocator, which cleans memory during allocation and deallocation,
- tests using that allocator to vector.

This patch is part of our efforts to add support for ASan annotations with every
allocator.

This commit adds a new allocator for testing purposes only. The safe allocator
ensures that memory is cleand (zeroed) during allocation and deallocation, and
is intendted to test ASan annotations for every allocator in std::vector.
Check: D136765

Those tests should work correctly, even if support for every allocator in std::vector
is not yet available.

Support in ASan API was added here: rGdd1b7b797a116eed588fd752fbe61d34deeb24e4
