drivers/libusb_helper: introduce oocd_libusb_dev_mem_alloc() helper

On some systems (at least Windows/CYGWIN and macOS) libusb_dev_mem_alloc()
simply returns NULL.

Use the result of the very first libusb_dev_mem_alloc() call to decide
if the underlining system supports dev mem allocation or we should
fall-back to plain heap malloc().

From the decision time on, keep using the selected type of memory allocator
and deallocator.
