RFR: 8236736: Change notproduct JVM flags to develop flags

Tue Apr 2 13:23:16 UTC 2024

Remove the notproduct distinction for command line options, rather than trying to wrestle the macros to fix the bug that they've been treated as develop options for some time now.  This simplifies the command line option macros.

Tested with tier1-4, tier1 on Oracle platforms.  Also built shenandoah.
