[Enhancement] Provide additional configuration options to denote situations where physical damage resistances don't apply

[Pjb518]

Instead of adding a huge number of combinations for different physical resistances and the ways that they can be undermined, we should provide a secondary table in the resistances and immunities dialogs, where selected resistances are on one axis, and materials that can undermine those defences are on the other.

	Adamantine	Magical	Silvered
Bludgeoning		✅
Piercing			✅
Slashing	✅		✅

From this information, we can group similar patterns and provide concise summaries for the character's resistances, without users having to rely on the custom field.
