GH-103082: Filter LINE events in VM, to simplify tool implementation. (GH-104387)

Browse source 
When monitoring LINE events, instrument all instructions that can have a predecessor on a different line.
Then check that the a new line has been hit in the instrumentation code.
This brings the behavior closer to that of 3.11, simplifying implementation and porting of tools.
