Refactor Jetbrains IDEs

[jan-vcapgemini]

PR #480 was merged but this is not really completed:

• Introduce an abstract class IdeaBasedIdeToolCommandlet between IdeToolCommandlet and its current implementations Intellij and AndroidStudio. There might come support for additional such IDEs to IDEasy in the future (PyCharm, WebStorm, etc.).
• Extract common functionalities to the new abstract base class.
  • IMHO plugin installation is the same for all IDEA/JetBrains IDEs except for some parameterization of the download URL and the IDE folder name in the plugins folder. UPDATE: This is more or less a duplicate of Add plugin installation support to AndroidStudio #479 - at least that would be the best way to resolve Add plugin installation support to AndroidStudio #479 instead of copy&paste approach.
  • IDEA_PROPERTIES mechanism is the same for all IDEA/JetBrains IDEs only the name of the environment variable differs. The Variable value differs per workspace. Therefore setting it once in postInstall with a fixed workspace name is buggy since we write the resolved workspace name in there instead of ${WORKSPACE}. We could better "export" this property via ProcessContext for each call of that IDE instead of writing to ide.properties files. Also it seems an existing flaw that we use the same-filename for different IDE products: See android-studio and IntelliJ. As both files have different content, they also must have different filenames as otherwise one overrides the other. - done with this commit.
  • The getBinaryName() problem is the same for all IDEA/JetBrains IDEs. The current solution is still not nice. I would prefer a postInstall hook that creates a simple wrapper bash script if the default command is not already present. So create bash script studio that only calls studio64.exe $*, etc. UPDATE: This point is more or less a duplicate of Generalize intellij OS startup command for all OS's #440 (but that issue is only about IntelliJ).
