[libc++][string] Add regression test for sized new/delete bug (#110210)
eea5e7e 
This is regression test for #90292.

Allocator used in test is very similar to test_allocator.
However, reproducer requires size_type of the string
to be 64bit, but test_allocator uses 32bit.

32bit size_type makes `sizeof(string::__long)` to be 16,
but the alignment issue fixed with #90292 is only triggered
with default `sizeof(string::__long)` which is 24.

Fixes #92128.
