RFR: 8318484: Initial version of cdsConfig.hpp

[Ioi Lam]

This is the first step for [JDK-8318483 - Move CDS configuration management into cdsConfig.hpp](https://bugs.openjdk.org/browse/JDK-8318483)

- Remove `Arguments::is_dumping_archive()` and `Arguments assert_is_dumping_archive()`
- Add the following new APIs


class CDSConfig {
  static bool is_dumping_archive();
  static bool is_dumping_static_archive();
  static bool is_dumping_dynamic_archive();
  static bool is_dumping_heap();
};


- Convert some use of `DumpSharedSpaces` and `DynamicDumpSharedSpaces` to these new APIs

(More APIs will be added in future sub tasks of [JDK-8318483](https://bugs.openjdk.org/browse/JDK-8318483))
