Add tests for the size threshold of the proxy library
The proxyLib_size_threshold_* tests test the size threshold of the proxy library. The size threshold is set to 64 bytes in this test, so all allocations of: 1) size < 64 go through the default system allocator and (umfPoolByPtr(ptr_size < 64) == nullptr) 2) size >= 64 go through the proxy lib allocator and (umfPoolByPtr(ptr_size >= 64) != nullptr).
