Rename to beforeProcessEpoch and afterProcessEpoch

[dapplion]

Motivation

Working on optimizing the state transition function caches, I find more intuitive to rename this functions to

beforeProcessEpoch()
processEpoch()
afterProcessEpoch()

Since they do more that just preparing the epoch process.

Description

• Rename prepareEpochProcessState -> beforeProcessEpoch
• Rename rotateEpochs -> afterProcessEpoch
