HDF5 API test updates (#3835) 
* HDF5 API test updates

Removed test duplication from bringing API tests
back into the library from external VOL tests
repo

Synced changes between API tests and library's
tests

Updated API tests CMake code to directly use and
install testhdf5, testphdf5, etc. instead of
creating duplicate binaries

Added new h5_using_native_vol() test function to
determine whether the VOL connector being used
is (or the VOL connector stack being used resolves
to) the native VOL connector

* Remove duplicate variable
