Enforce deterministic iteration order for sandbox fibers
...
I've changed the sandbox fibers in libretro builds to be stored in a
linked list, with an unordered map mapping fiber keys to linked list
nodes for efficient lookup. The original implementation was just having
all the fibers in an unordered map.
The new implementation has the benefit that fibers are always iterated
in the same order on every platform, which allows save state creation to
be more deterministic.

Prevent unaligned memory accesses in libretro builds

These are undefined behaviour. All memory accesses need to be aligned.
For unaligned memory accesses, we have to use memcpy.

Fix edge case in pointer unswizzling algorithm for libretro save state serialization
...
If there are two Ruby objects, A and B, that are both no longer used
(i.e. they're able to be freed by the Ruby garbage collector), and A
references B, then it's possible for the Ruby garbage collector to free
B but not also free A in the same garbage collection cycle.
The pointer unswizzling algorithm currently crashes when the garbage
collector does this because the object A will still be in
`sb()->objects` but B will not be, and so save state serialization will
still try to serialize A. When the pointer unswizzling algorithm tries
to serialize all the other objects A references and cannot find the
referenced object B, the program crashes.

Serialize PRNG state in libretro save states

Save states in libretro builds now also contain the state of the
pseudorandom number generator used to implement the WASI `random_get`
function for better save state determinism.
I've also changed the PRNG from MT19937 to PCG.

Implement reinitializing OpenGL objects in libretro builds

Libretro provides a way to detect when the OpenGL context is destroyed,

commit implements reinitializing all OpenGL objects when this happens so
that the graphics continue to function in this case.
