Quodss/urwasm stateful

[dozreg-toplud]

Depends on urbit/wasm3#1

Adds stateful jet for ++run:wasm-lia:

• Defines two sets of allocators for m3 structs and codepages;
• Updates _reduce_monad to enable computation suspension;
• Adds _get_state to load wasm3 state from persistent cache table;
• Adds _move_state to store wasm3 state in persistent cache table with the new key and remove an entry with the old key;
• updates u3we_lia_run version due to return type change in Quodss/urwasm stateful urbit#7128;

Misc:
builtins for c3_d, motes

TODO:

• optimizations:
  • arena on a slab to prevent copying data one more time;
  • smarter m3 struct realloc (currently wastes memory since wasm3 uses realloc to grow dynamic arrays);
