* When the cause of destruction was world-induced (CanBeAt check failed) there is no tool. Pass the nullptr directly to ConvertToPickups and let it handle it.
* Fixes#4795
- Remove unused a_Digger parameter to ConvertToPickups.
This is only overridden false in Vines and Snow. It is called when a CanBeAt check fails, to determine whether DropBlockAsPickups is called. However, Vines and Snow already drop nothing without the right tool, so this function is superfluous.
* BlockHandler initialisation is a constant expression
If we can't make it all namespaces, this is the next best I guess.
+ Tag handlers constexpr, const as needed
+ Inherit constructors
* Privatise handler functions
* More constexpr

This was mostly done automatically and then visually inspected for obvious errors.
All //-style comments should have a 2-space separation from the code, and 1 space after the comment sign.
Changed the signitures of the following to use interfaces:
GetPlacementBlockTypeMeta
OnPlaced
OnPlacedByPlayer
OnDestroyed
OnNeighbourChanged
NeighbourChanged
OnUse
CanBeAt
