    Introduce new module mount implementation · a73e7e9f

    Rewrite the whole module mounting logic from scratch.
    Even the algorithm is different compared to the old one.
    
    This new design focuses on a few key points:
    - Modular: Custom nodes can be injected into the mount tree.
      It's the main reason for starting the rewrite (needed for Android 11)
    - Efficient: Compared to the existing implementation, this is the most
      efficient (both in terms of computation and memory usage) design I
      currently can come up with.
    - Accurate: The old mounting logic relies on handling specifically every
      edge case I can think of. During this rewrite I actually found some
      cases that the old design does not handle properly. This new design is
      architected in a way (node types and its rankings) that it should
      handle edge cases all by itself when constructing mount trees.
