Add the possibility to disable dwarf source line information

[xarkes]

Is your feature request related to a problem? Please describe.

Currently if one wants to hide the information of source line, one has to do e asm.dwarf=false which might remove other useful dwarf information as well.
We discussed it in a PR for Cutter here rizinorg/cutter#2600 and I'll detail the solution we thought would be the best.

Describe the solution you'd like

• Rename asm.pdb.lines to asm.debug.lines
• When dwarf information is available:
  • If asm.dwarf=true and asm.debug.lines=false hide dwarf source line information
  • If asm.dwarf=false hide dwarf source line information anyways

Feel free to edit this issue in order to add more details.

I think what you suggest make sense and it should be fairly easy to do, however in practice at the moment I am not sure which additional information get included with asm.dwarf=true. Do you have an example where this is an actual problem? Apart from that anyway, the feature sounds good to me and makes sense.

@thestr4ng3r maybe you could include this in our DWARF refactoring PR too?

Yes, this can be done. But line information is conceptually independent of dwarf as dwarf is just one possible source of information for it.
