Welding Tool Usage Checks

[Atermonera]

Brief description of the issue

Doing a search for TOOL_WELDER should find most of the spots. Calling out further spots here for tracking: Plasma cutter is a welding tool https://github.com/PolarisSS13/Polaris/blob/848d3ed523c46e3d6cb680bee1a814907a986529/code/game/objects/structures/girders.dm#L162
