Parser should allow parsing of JavaSources when dependencies changed

[fabapp2]

What needs to be done

The RewriteProjectParser should be refactored to allow parsing a list of JavaSources with a given classpath.

Why it needs to be done

#858 is blocked by #871 which is blocked by this issue.

Acceptance Criteria

• All markers are updated and updated

Additional Information

Example

Given a reactor build with four pom.xml: parent, A, B, and C where A depends on B and B depends on C.

When a dependency is added to B and the classpath changed

Then modules A and B must be parsed again to resolve the new types added.
While C is not required to be parsed again (it didn't change), the types provided by C must be made available when parsing B, and B's types must be made available when parsing C and so forth.

Learnings

See #971

• The JavaParser instance keeps type information as state.
• To reuse previously built type information (the type information of C in the example above) it must be provided when re-parsing the next higher modules in the reactor hierarchy (B).
• Sharing the TypeCache is not enough
• The state is kept after calling reset().
• Keeping and reusing the JavaParser instance itself could be possible, it can be provided through a Marker, similar to JavaSourceSet.
