Add support for selecting objects, structures and jigsaw for /locate (vanilla)

[svdgoor]

Is your feature request related to a problem? Please describe. As we are replacing vanilla structures (which is a good thing), we should keep support for eyes of ender and the maps cartographer villagers give.

Describe the solution you'd like Have /locate point towards selected structures by configurations them by name.

Describe alternatives you've considered Disabling eyes of ender and cartographer maps

Additional context Make sure to do either solution or making cartographers going to level 3 will crash the server (I think).

eyes of ender solution is wack. We should ideally use the .poi data to find (locate) objects by name. We should also look into object-specific settings such as respawning mobs (pillagers, guardians, drowned) etc.

Locating objects should become possible with the new Mantle system. #519

Alongside this I had the idea of maps (just like the maps traded with villagers, except pointing to customizable structures within the terrain generation.

Mantle find is good
