Remove (mentioning) recproofs for state tree, event log tree, read and write tree

[Ethan-000]

we are not using the advantage of recproofs for these trees which is batch membership proof openning and updating.

for the state tree the Old root and New root is over the entire leaves

for event log tree and the read and write tree they are not using recproofs because they change every block and they are reconstructed every block. they are not a subset of anything

should call our implementation durpmerp perhaps 😜 h.t @Daniel-Aaron-Bloom

note that Recproofs might be useful for other trees and usecases in the future

also checked the code when writing doc. the tree implementations are mostly good. should be fine with some small changes after removing mentionings of recproof
