Add a precompile allowing to send ZRC20 to be distributed to stakers

[lumtis]

Would depend or heavily reuse logic from: #2791

Add a precompile leveraging the fee pool of the Distribution module to distribute rewards to ZETA stakers: https://docs.cosmos.network/main/build/modules/distribution

Interface (to be finalized):

Precompile contract named Distribution:

distribute(address zrc20, uint256 amount) // send zrc20 to distribution pool, the contract manage the conversion into Cosmos token

To be consider: another function allow to create a distribution over time: distribute 1000 BTC over 4 weeks

Other consideration

To have an experience where users only interact with ZRC20s and EVM, we could extend the claim method implement in #2754 to automatically convert the claimed rewards into ZRC20s

Note:

• adding same restriction to only zrc20 as Add a precompile allowing to map ERC20s into bank tokens #2791 because permission would allow to spam the fee pool which is iterated at the end-blocker
• adding zeta-utility label as it allow to build application that rewards ZETA stakers
