Sergei Barannikov d3750412aa [TableGen][GISel] Improve dead register handling (#120426) ...

A dead implicit def wasn't marked as dead if it is also an implicit use.
The new approach should also be more straightforward and simplifies
future changes for supporting optional defs and physical register defs.
