Static support trait (#6044)

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.
