feat(ext/ffi): Callbacks (#14663 )

This commit adds support for unstable FFI
callbacks. A callback is registered using
the `Deno.UnsafeCallback` API.

The backing memory for the callback can 
be disposed of using `Deno.UnsafeCallback#close`.
It is not safe to pass the callback after calling
close.

Callbacks from other than the isolate thread
are not supported.
