Mezo Allocator will route tBTC tokens between Acre x Mezo. Mezo Allocator is the first pluggable contract to Acre system that will handle staking tBTC on various L2s/DeFi. Withdrawal part will be added in other commits.
- Added mainnet and sepolia addresses in Jsons for Mezo Portal - Added deployment script for Mezo Allocator contract. A fake random address is used for Mezo Portal when deploying on hardhat network. This is for testing purposes only.
At first Mezo Allocator will be Acre's dispatcher. Later on a proper dispatcher will be implemented and switched with the Mezo Allocator.
Dispatcher in the current form will be replaced in the future. For now, the role of the dispatcher contract will server the MezoAllocator contract since we do not have any other L2s/DeFi partners yet. Once we have it, it will be updated for the proper dispatcher that will include MezoAllocator.

It might happen that we'll need a data structure to support information like deposit creation and unclock time in case we shift from the zero time locks.
- Made Slither and Solhing happier - Renamed the tag name for Mezo Allocator
Here we change the deposit approach from tracking all the Mezo Deposits to having only a single deposit that accumulates all deposited tBTC by Acre into a single deposit. An "old" deposit is abondoned and balance is zeroed. A "new" deposit is created with a new id and a new balance is equal to the old balance + new requested amount.

We need to pull funds from Mezo Portal first before we can update the balance. This is because if amount > then the balance, it should revert. Otherwise, we'll get the underflow error.

In case there will be a need of pulling all the funds from Mezo we add a releaseDeposit function that can be called by the owner only.
Added NotMaintainer and NotStbtc to better understand the error if occurs.

Depends on #326 Mezo Allocator will serve as a first "dispatcher". We should remove the current outdated version of the Dispatcher contract that will be replaced by another contract in the future.

Depends on #314
This PR adds the first tBTC Allocator with depositing functionality only that will work with Mezo L2. The gateway for tBTC allocation on Mezo is called Mezo Portal and this is where tBTC are allocated from Acre. As of now, 100% of assets will flow to Mezo Portal upon staking in Acre. In the future the % of allocation might change once other L2/DeFi are introduced.
Deposits are created as "rolling" deposits, meaning that the "old" Acre's deposit is drained and all the assets are moved to a newly created deposit. A new id is assigned and replaces the old one. The "old" deposit with zero balance is abandoned.
Mezo Allocator now serves as a "Dispatcher" contract in stBTC because there is only one Mezo Allocator. Once we have more allocators, then the Dispatcher contract will need to be implemented and switched with the current Mezo Allocator contract in stBTC. MezoAllocator will be included in Dispatcher's authorized list of allocators.
