Set line number on the POP_TOP that follows a RETURN_GENERATOR #109923

Description

@iritkatriel

Currently the POP_TOP of a generator doesn't get a line number.
If we give it the same line number as the RETURN_GENERATOR and RESUME, that will reduce the size of the line number table.

The missing line number also got in my way while working on #109094.
