Add tests for filter order on read and write cases

Browse Source 
re: https://github.com/Unidata/netcdf-c/issues/1923
re: https://github.com/Unidata/netcdf-c/issues/1921

The issue was raised about the order of returned filter ids
for nc_inq_var_filter_ids() when creating a file as opposed
to later reading the file.

For creation, the order is the same as the order in which the
calls to nc_def_var_filter() occur.
However, after the file is closed and then reopened for reading,
the question was raised if the returned order is the same or the reverse.
In fact the order is the same in both cases.

This PR extends the existing filter order testcase to check the create
versus read orders. This also required changing the H5Znoop(1) filters
in the plugins directory.

Misc. Unrelated Changes
1. fix calls to fdopen under windows
2. Temporarily suppres the nczarr_tests/run_chunkcases test
   since it seems to be causing problems with github actions.
