Now the information about the constant pool entries to be pre-resolved in the assembly phase is only conveyed through FinalImageRecipes, making it easier to trace the resolution of CP entries.

This is because `AOTConstantPoolResolver::preresolve_field_and_method_cp_entries` was only looking for `getfield` and `putfield` bytecodes, but during the training run, these bytecodes may get replaced by their "fast" versions by the interpreter, or by the "nofast" versions during preimage dumping. So I have to add cases for handling the "fast" and "nofast" variations of the bytecodes as well.
