ProtoRev adjustments [Proposal 709/710]

[JohnnyWyles]

Background

This issue asks for the implementation of Proposals 709and 710.

These allocate ProtoRev by:

• Sending any OSMO revenue to the null address
• Sending any non-OSMO revenue to the community pool.

Suggested Design

This would need three main changes

Revenue deposit location

The locations at which the assets are deposited once obtained, after Skip's share of revenue is taken.

• Currently this is the ProtoRev module account.
• OSMO would instead switch the null address.
• Non-OSMO would be sent to the community pool.

Existing assets move

Existing assets in the module account would need to be moved to the above locations, ensuring that none are left behind. This can take place as part of the initial software upgrade, a routine sweep at epoch, or a further spend proposal.

Exclusion of null address from supply to form the burn mechanic

Detailed in #5606

Acceptance Criteria

No assets remain in the protorev module account.
Community pool accumulates all non-OSMO revenue from Protorev
Null address accumulates all OSMO revenue from Protorev
