Rewrite the memory management code for Nintendo Switch
The first implementation was naive and did not account for multiple
memory allocations. However, this implementation may still be
incomplete. Currently, when running applications, the code runs fine.
When the application is exited via code (the end of the program is
reached or quit() is called), the Switch will crash. Not sure why this
happens, but I suspect it is from Nim memory allocations.
I suspect the memory allocations because when I compile the helloworld
application without any Nim allocations (just C function calls) and use
`--gc:none` as a compile option, the application exits fine.
