Bump lanes config

[mpapierski]

This PR bumps lane config based on mainnet data activity
Impact:

• Install/upgrade lane and lane no.3 (aka biggest wasm lane) from 100CSPR to 1000CSPR -> this should cover 98% of all Wasm interactions (session & stored).
• Lane 4 already covers 58% of session code and 0.5% of smart contract interactions
• Lane (no.5) is bumped from 3CSPR to 5CSPR -> will now cover about 40% of all session codes (up from 30%) and 99.5% of smart contracts (up from 99.1%)

Busy wasms were validated with new settings.

Wasm saturated block will consume about 1600CSPR of gas (increased from 500CSPR), leaving 25CSPR worth of computation for native contract calls (e.g., transfers, and auction contracts). Current mainnet usage data suggests 70% of chain interactions are session/smart contracts and 30% are native transfers.
