chore: add v4 upgrade handler

[RiccardoM]

Description

This PR adds the v4 upgrade handler that takes care of removing all markets and currency pairs from the x/marketmap and x/oracle modules except the ones that are related to TIA .

This was done in order to reduce the amount of data stored per each block, since we do not use any currency pair outside of TIA/USD and its derivates inside our modules.

Closes: MILK-179
