[WIP] Add Developer build mode to CMake (#1659)

* Add Developer build mode to CMake

* Set a few CMake variables for Developer build modes

* Refactor enabling of debug and developer-level compile definitions

* Convert cache debugging macros to normal ifdef style

Normal ifdef-style instead of if-style allows build system to define macros
without warning about redefining macros with different values (0 vs. 1)

* Add HDF5 Developer compile definitions to testing files

* Temporarily disable -fanalyzer flag for GCC 12+ Developer builds
