feat: mnlistdiff move nversion to first position (#5450)

Browse Source 
## Issue being fixed or feature implemented

Version field should always be the first field of a message for better
readibility.

## What was done?

- Introduced new protocol version `MNLISTDIFF_VERSION_ORDER` (`70229`).
- `nVersion` serialisation order is changed for clients with protocol
version greater than or equal to `70229`.
- For clients with protocol version >= `70225` and < `70229` the old
order is used: can be deprecated in the future.
- Increased functional test P2P mininode's protocol version to `70229`.

## How Has This Been Tested?
`feature_llmq_rotation.py` with new protocol version.
