Modify zkSync MetaVesT for Yearn BORG director compensation

[Detoo]

Primary goal is to keep changes minimum. The real feature changes are only in the following two files:

• src/BaseAllocation.sol
• src/MetaVesTController.sol

Changes are for (1) contracts size & stack-too-deep fixes, and (2) replacing capped minter interface with regular ERC20 tokens. Most logic are not new and directly restored from main branch, as shown and commented below.

The remaining changes are all scripts & tests.

	) revert MetaVesTController_AmountNotApprovedForTransferFrom();
