common: Remove memory_util.cpp/.h

Everything from here is completely unused and also written with the
notion of supporting 32-bit architecture variants in mind. Given the
Switch itself is on a 64-bit architecture, we won't be supporting 32-bit
architectures. If we need specific allocation functions in the future,
it's likely more worthwhile to new functions for that purpose.
