RFR: 8320147: Remove DumpSharedSpaces [v2]

[Ioi Lam]

> One more PR for cleanup with cdsConfig.hpp:
> 
> Replace the global variable `DumpSharedSpaces` with `CDSConfig::is_dumping_static_archive()`.
> 
> Note: some mis-uses of `DumpSharedSpaces` need to be replaced with `CDSConfig::is_dumping_heap()` or `CDSConfig::is_dumping_full_module_graph()`
