Disable pointing for tools

[Wuzzy2]

I request to be able to completely disable pointing for tools (including the hand).

To implement this, I request to simply interpret the value range=0 as a special value which disables pointing. Currently, this almost works, but when you are inside a node, you still point it. It seems to be impossible to force the player to be completely unable to point something. There are certain uses for this (see below). There's also a bug: If you set range=0 for the hand, it does not work at all. The range remains at the default 4 if you have the hand selected, but the range is 0 if you have an item on hand (e.g. cobblestone).

Rationale: This is an easy and reliable way to completely disable rightclicking, mining and punching any nodes, entities or whatever.

Use cases:

• Prevent punching or mining anything while the player is in a bed (using a hand overwrite)
• Add a player status which temporarily disables hand pointing
• Add a teleporter beacon tool which, when you leftclick, saves the position on which you stand. For tools like this, pointing wouldn't make much sense

Any core dev support? (i'm neutral).

Reopen. I realised i support this as a duplicate issue was opened which i support #10355

As suggested in #14742, I'd like a solution like range = -1
