RFR: 8277481: Obsolete seldom used CDS flags [v2]

[Harold Seigel]

> Please review this change to obsolete deprecated CDS options UseSharedSpaces, RequireSharedSpaces, DynamicDumpSharedSpaces, and DumpSharedSpaces.  The change was tested by running Mach5 tiers 1-2 on Linux, Mac OS, and Windows and Mach5 tiers 3-5 on Linux x64 and Windows x64.
> 
> The use of UseSharedSpaces in ps_core_common.c was tested on Mac OS x64 by temporarily removing serviceability/sa/ClhsdbPmap.java#core from the problem list.
> 
> Thanks! Harold
