Remove support for Visio and POTM files

Actually we never supported Visio files but we are failing hard (kill a node) when that kind of file is provided.
See https://github.com/elastic/elasticsearch/pull/22079#issuecomment-277035357

This commits excludes Visio parsing from Tika so it does not fail anymore but returns empty content instead.

As a side effect, it also removes support for POTM files.

Closes #22077.
