Dennis Heimbigner 730aa1f6bc Improve the building of NCZARR S3 support in CMake and Autoconf
There were some irregularities in the flags for handling NCZarr S3 support.

The primary change is to regularize the flags controlling this to the following.

1. Automake: --enable-nczarr-s3 and CMake: ENABLE_NCZARR_S3
2. Automake: --enable-nczarr-s3-tests and CMake: ENABLE_NCZARR_S3_TESTS

Flag 1 indicates that NCZarr should be built with S3 support enabled.
Flag 2 indicates that the NCZarr S3 tests should be run

These two flags are separate because running the NCZarr S3 tests
requires access to protected S3 resources. Currently, running
these tests is restricted to Unidata personnel. However, users
may want to enable S3 support even if they cannot run the tests.
It is, of course, an error to specify 2 without specifying 1.

Additionally, if the AWS S3 SDK library is not found, then the NCZARR S3
support and testing must be disabled. Otherwise an error is signaled
during the build.

Some of these NCZarr and S3 changes are propagated to nc-config.

Misc. Other Changes:

1. Allow testing for CYGWIN or MSVC in shell scripts.
2. Add specific test for HDF5 library version 1.10.6.
   This is encoded as "HDF5_UTF8_PATHS" because that is the first
   version where HDF5 properly supports it under Windows. This is used
   in hdf5internal/nc4_ndf5_ansi_to_utf8.
3. Add a AM Conditional -- AX_IGNORE -- for use in testing
   when it is desirable to temporarily suppress Makefile code.
4. Add MULTIFILTER flag to CMakeLists.txt

# Define a function that attempts to locate a
# plugin with a given canonical name.
# Assumptions:
# 1. plugins is a top-level directory
# Inputs:
# $1 is the canonical name
# $2 is 1 if we are running under cmake
# $3 is 1 if we are running using Visual Studio, blank otherwise
# $4 is the build type; only used if $3 is 1
# Outputs:
# return code is 0 is success, 1 if failed
# Variable HDF5_PLUGIN_LIB is set to the library file name
# Variable HDF5_PLUGIN_PATH is setthe absolute path to the
# directory containing the plugin library file
# Local variables are prefixed with FP_
#
# Note: we assume that the use of the CMAKE_BUILD_TYPE
# is obviated by setting the LIBRARY_OUTPUT_DIRECTORY
