[LLDB][DYLD] Remove logic around not rebasing when main executable has a load address

[Jlalond]

This is a part of #109477 that I'm making into it's own patch. Here we remove logic from the DYLD that prevents it's logic from running if the main executable already has a load address. Instead we let the DYLD fully determine what should be loaded and what shouldn't.
