Refactor, improve, and rename canUseTopic to be can_perform_action (#73434)

This builds on what #69790 did and improved the code even further.
Notable things:
- `Topic()` is a deprecated proc in our codebase (replaced with
Javascript tgui) so it makes sense to rename `canUseTopic` to
`can_perform_action` which is more straightforward in what it does.
- Positional and named arguments have been converted into a easier to
use `action_bitflag`
- The bitflags adds some new checks you can use like: `NEED_GRAVITY |
NEED_LITERACY | NEED_LIGHT` when you want to perform an action.
- Redundant, duplicate, or dead code has been removed.
- Fixes several runtimes where `canUseTopic` was being called without a
proper target (IV drips, gibber, food processor)
- Better documentation for the proc and bitflags with examples
