[Refactoring] Fix usage of rawtypes

[Shadow-Devil]

Purpose

To ensure type-safety, generics should always be filled out (= no more raw types).

Some issues I encountered:

• Some casts could not easily be made, like converting a List<Object> to a List<String>. For this I used the approach from this Stackoverflow post to cast List<Object> -> List<?> -> List<String>.
• Some generics can't be filled out since they are returned by a library or because of ServiceLoader.load(Service.class) which does not work with generics.
• In TableValueImpl.entrySet() there was a type error which I could only fix with a semantic change. But I think this was a bug.

@Shadow-Devil Still the windows build pipeline is failing

[Shadow-Devil]

With a very strange error:

The :jballerina-debugger-integration-test:jacocoMergeExec task failed.
Unable to read execution data file D:\a\ballerina-lang\ballerina-lang\tests\jballerina-debugger-integration-test\build\jacoco\debugger-runtime-test.exec
> (No message provided)

@gimantha Could you only restart the windows pipeline please?
