[PROP #1][APPROVED] Increase max_bytes and max_gas in BlockParams to increase max TPS

Since the launch of the Dymension blockchain (chain-id: dymension_1100-1), and due to the high load, transaction processing is at times very slow. After discussion with multiple teams including Skip and confirmation on the dymension testnet (chain-id: blumbus_111-1), we’ve come to the conclusion that the main culprit are the current BlockParams, specifically max_gas.

The core team along with partners have found that the current max_gas to be a limiting factor for TPS, leaving more than an order of magnitude of block data capacity non-utilized.
Targeted tests showed significant increase in TPS while managing to fully utilize block size (5mb on testnet. chain-id: blumbus_111-1).

As such, the core team recommendation is to increase two BlockParams namely max_gas and max_bytes. Specifically, the proposal is to increase max_gas to 400000000 (i.e. 400 million) and max_bytes to 5242880 (i.e. 5mb) which is the upper limit of the p2p storms vulnerability report (P2P Storms: Vulnerability Report - Google Docs).
