Description
What is the feature you'd like to have?
Rename imported ordinal function to its original name which can be get from pdb.
Is your feature request related to a problem?
Use case: I am dealing with a crackme that uses MFC, and the import functions are all like Ordinal_mfc90u_286. I loaded the MFC DLL in binja and applied the PDB. Is there a simple way to rename all ordinal functions in crackme based on the information of the MFC dll that has loaded the PDB?
Are any alternative solutions acceptable?
No

Research direction
Start by investigating how Binary Ninja represents imported ordinal functions and how a TypeLibrary could associate MFC ordinals with symbols recovered from a PDB-loaded MFC DLL. Confirm the expected behavior using the crackme and MFC examples in the issue; done means ordinal imports are renamed to their original functions through the proposed TypeLibrary.
