RFR: 8327138: Clean up status management in cdsConfig.hpp and CDS.java [v2]

[Ioi Lam]

> A few clean ups:
> 
> 1. Rename functions like "`s_loading_full_module_graph()` to `is_using_full_module_graph()`. The meaning of "loading" is not clear: it might be interpreted as to cover only the period where the artifact is being loaded, but not the period after the artifact is completely loaded. However, the function is meant to cover both periods, so "using" is a more precise term.
> 
> 2. The cumbersome sounding `disable_loading_full_module_graph()` is changed to `stop_using_full_module_graph()`, etc.
> 
> 3. The status of `is_using_optimized_module_handling()` is moved from metaspaceShared.hpp to cdsConfig.hpp, to be consolidated with other types of CDS status.
> 
> 4. The status of CDS was communicated to the Java class `jdk.internal.misc.CDS` by ad-hoc native methods. This is now changed to a single method, `CDS.getCDSConfigStatus()` that returns a bit field. That way we don't need to add a new native method for each type of status.
> 
> 5. `CDS.isDumpingClassList()` was a misnomer. It's changed to `CDS.isLoggingLambdaFormInvokers()`.
