Make more use of <tool>_act (#64375)

Replaces a bunch of tool behavior checks in attackby to instead use the respective procs.
For instance, the behavior under a if(I.tool_behaviour == TOOL_SCREWDRIVER) check in attackby() will instead be found under that same object's screwdriver_act() proc. This is the first of a few PRs that I'd like to make to address this, since there's going to be a lot of code shuffled around.

This shouldn't have any impact on players, though some super observant folks might notice that they don't bash some items with tools when they meant to interact with them. I've tested all of these in game and they seem to still have the same behavior as before.
