  Block the GC while executing a proxied method

Proxy runs methods on the target with the target's interp. If GC is
triggered during this run, the foreign interp's GC could find our PMCs
on the call stack. It would also not find any PMCs which are on the
foreign interp's callstack. And most of all it could be that the foreign
interp also starts collecting garbage at the same time...

So we block the foreign GC to prevent this from happening.

  Log Message:
  -----------
  Use Parrot_thread_create_proxy to create proxies

Proxy's methods create proxies for returned objects. Before this fix, it
did this by calling Parrot_pmc_new_init itself but using the wrong (the
proxied) interp, so all Proxy objects originating from proxied method
calls would be allocated on the wrong interp.

Use Parrot_thread_create_proxy which handles this correctly, reducing
the places in which proxies are created.
