Subject: [PATCH] ARROW-15511: [Python][C++] Remove reference management in
 numpy indexer

It appears all usages don't escape the scope of methods so a strong reference should already be in place.
This is necessary because Ndarray1DIndexer can be used without the GIL held.

Closes #12314 from emkornfield/ARROW-15511
