Decouple sbm-support-rewrite from Maven

[fabapp2]

What needs to be done

The RewriteProjectParser in sbm-support-rewrite starts Maven to provide the input data for OpenRewrite's Maven plugin code. It should be refactored to not require Maven.

Why it needs to be done

• Starting the Plexus container from within a Spring application fails because the Plexus container does not find all components and can't start up. This only happens in Spring Boot applications indicating a conflict when loading jars from BOOT-INF/libs.
• When using Maven to parse the poms, the project must always be a valid Maven project and thus every recipe must leave the application in a buildable state. Otherwise the migration will be stuck and running other recipes is not possible.
• The parser uses Maven classes and is therefore coupled to java.io.File requiring the resources to exist on the filesystem. Previously Springs Resource abstraction was used which allowed "synthetic" dummy resources that didn't need to exist on FS. Removing the need for Maven would allow using Resources again.
