ENH: CosmoTools ParaView plugin updates

This commit updates the CosmoTools plugins for the
current ParaView master and later ParaView releases.
Notably, the "CosmologyToolsReaders.xml" is removed
since it is no longer needed on the client. The
CMakeLists file was updated accordingly. Further,
"CosmologyToolsFilters.xml" was renamed to
"CosmoToolsFilters.xml" and likewise, the toolbar name
was changed to "CosmoTools" instead of "CosmologyTools"
