Dennis Heimbigner 7b09290a3a Improve filter installation process to avoid use of an extra shell script
re: https://github.com/Unidata/netcdf-c/issues/2338
re: https://github.com/Unidata/netcdf-c/issues/2294

In issue https://github.com/Unidata/netcdf-c/issues/2338,
Ed Hartnett suggested a better way to install filters to a user
defined location -- for Automake, anyway.

This PR implements that suggestion. It turns out to be more
complicated than it appears, so there are fair number of changes;
mostly to shell scripts. Most of the change is in plugins/Makefile.am.

NOTE: this PR still does NOT address the use of HDF5_PLUGIN_PATH
as the default; this turns out to be complex when dealing with NCZarr.
So this will be addressed in a subsequent post 4.9.0 PR.

## Misc. Changes
1. Record the occurrences of incomplete codecs in libnczarr so that
   they can be included in _Codecs attribute correctly. This allows
   users to see what missing filters are referenced in the Zarr file.
   Primarily affects libnczarr/zfilter.[ch]. Also required creating a
   new no-effect filter: H5Zunknown.c.
2. Move the unknown filter test to a separate test file.
3. Incorporates PR https://github.com/Unidata/netcdf-c/pull/2343
