Bug 1864960 - Make assertion about cache alignment of mark bits into a static_assert r=sfink
The problem was the dynamic assertion ended up reading the chunk header in
Arena::checkAddress(), and for empty chunks we have told ASAN that shouldn't be
accessed by this point.
The fix is a more complicated set of static assertions to check everything is
aligned as we expect.
