Added StaticSupportTrait for blocks which require unconditional support
dynamic support requirements, such as those presented by item frames and torches, are not included.
in addition, double blocks, such as tallgrass, small dripleaf and doors, do not cooperate well with this, so they are also not included.
some blocks which could be migrated (such as chorus plant) were skipped due to unresolved problems.
closes#5936
This implements all of the basic activation logic for pressure plates.
It also introduces a PressurePlateUpdateEvent, which is called in pulses when entities are standing on top of the plate and when it deactivates. Deactivation can be detected by checking if the list of activating entities is empty.

this switches from a 'can be supported by' concept to a 'can stay at this position' paradigm, which requires way less boilerplate code.
there may be further improvements we can make from here, such as adding traits, but this is a good first step.
