feat: Implement fraudproof generation mode in cosmos-sdk

Description

Before: When an optimint full node finds a fraudulent block, it tells cosmos-sdk to go into fraudproof generation mode.

After: optimint can supply cosmos-sdk with a fraudulent block and tell it to actually generate a fraudproof.

In the fraudproof generation mode, a cosmos-sdk app reverts its state to a previous state before the fraudulent block was applied and enables tracing for modules specified by optimint.

Parts covered from the cycle of a fraudproof:

Optimint Full Node (Producer of fraudproof)

In the fraudproof generation mode, a cosmos-sdk app reverts its state to a previous state before the fraudulent block is applied and enables tracing.

Builds on top of #256

Closes: #249
