Set NVHPC maximum optimization level to -O1 for now (#3800) 
* Set NVHPC maximum optimization level to -O1 for now

Compiling HDF5 with NVHPC 23.5 - 23.9 results in test failures in
4 different test files that need to be resolved. Since those tests
pass with an optimization level of -O1 (and -O0) and it is currently
unclear whether the test failures are due to issues in HDF5 or issues
in the 'nvc' compiler, set the maximum optimization level for NVHPC
to -O1 until the test failures are resolved.

* Disable nvhpc Java testing in CMake and amend known issues

* Re-enable testing of Autotools nvhpc
