Some access wideners are unused

[haykam821]

Access wideners relating to block and item predicate arguments don't seem to be used, since Client Commands reimplements them entirely:

https://github.com/Earthcomputer/clientcommands/blob/2d7f4a04c0a18cb72f3bd70523a1a5655ce5e09e/src/main/resources/clientcommands.aw#L4-L6

The mod compiles just fine if these access wideners are removed.
