Summary

Bugfixes "Nested pickups using (g) interface"

Purpose of change

Nested pickups were not working as intended.
Looking at couple of issues, there were instances where an item was flagged as 'valid' for picking up (using (g) menu), but was not actually picked up correctly because of a mismatch of intended functionality.

Found a couple of (slightly) related issues, among others: #54725 #53807

Describe the solution

This PR looks to streamline checks between character::can_pickVolume to item::can_contain, and item::best_pocket functionality, while also using recursion to allow deeply-nested pickups (i.e. socks -> tin -> pot -> bucket -> backpack) if the volume allows for it.

Describe alternatives you've considered

A smaller fix could be made just to item::can_contain to streamline intended functionality.
Deeply nested pockets would not be possible, but items would also not be flagged as 'valid' pickup as they are now.

Testing

Thoroughly tested using different related issues as a base, namely using the attached save from #54725.
Using the save, one can play around with the different containers to see if nesting is actually working as intended.

Additional context

Trying to pickup too many items in one go is still possible, and fails silently (i.e. trying to pickup two stones, but one fails because inventory is full after picking up the first). This should still be fixed, but I thought it'd be out of scope for this 'fix'.

Removed (slightly related) code duplication between character::can_pickVolume and character::canPickVolume_partial.
Replaced contain_code for item_pocket::can_contain and item_pocket::is_compatible.

A followup issue would be solving multi-pickup cancellation due to full inventory (either prevent it, or give the player a headsup).

There are quite some discrepancies between can_contain and
best_pocket functionality. This commit looks to fix that and actually
allow nested pockets to work properly as long as there is space.

Apologies for the mess. Github does not agree with rebases on branches for existing PRs. Had to change the target branch from- and back to fix.

You need to force push after rebasing.
