Update Cobalt to 0.7

- Timeouts are now driven by an interrupt system, rather than polling.
   While we do not impose memory limits, this should close #1333.

 - Update the table library to largely match Lua 5.4:
    - Add table.move
    - Table methods (with the exception of foreach/foreachi) now use
      metamethods (closes #1088).
   There's still some remaining quirks (for instance, table.insert
   accepts values out-of-bounds), but I think that's fine.

 - Cobalt's threaded-coroutine system is gone (load now supports
   yielding), so we no longer track coroutine metrics.

 - Type errors now use __name. See #1355, though this does not apply to
   CC methods (either on the Java or CraftOS side), so is not enough to
   resolve it.

See https://github.com/SquidDev/Cobalt/compare/v0.6.0...v0.7.0 for the
full delta.
