  [C-API][ORC] Add C API to suspend lookups during definition generation.

Slow definition generators may suspend lookups to temporarily release the
session lock, allowing unrelated lookups to proceed.

Using this functionality is discouraged: it is best to make definition
generation fast, rather than suspending the lookup. As a last resort where
this is not possible, suspension may be used.
