[Code] Update perlbind to 1.1.0 (#4529)

- Adds a perl::ref alias for perl::reference

- Optimizes array return pushes by accessing SV* values directly instead
  of using operator[] scalar_proxy

- Allows functions with a perl::hash parameter to accept hashes with any
  scalar key type instead of requiring explicit string keys

  e.g., foo(123 => 1) will now work on functions accepting a perl::hash
