Security audit for collections royalties marketplaces

Description
Based on the proposal passed [here](https://governance.decentraland.org/proposal/?id=b70c59d0-09c5-11ec-a4d1-8d5d2cba0825) + some free time I took the chance to upgrade the implementation of the Marketplace & Bid smart contracts to include royalties for collection creators/item beneficiaries. It is **ONLY IN POLYGON** where UG collections are being created. For the time being, royalties are going to be calculated following: - Each token is an item kind. You may know that each item can have a beneficiary which is used for primary sales. If the item has a beneficiary, the royalties will go to the item's beneficiary. If not. - Royalties will go to the collection creator. The implementation of how the royalties receiver is calculated can be easily replaced by a new one. To understand how it can be done if you are tech, refer [here](https://github.com/decentraland/marketplace-contracts/blob/feat/marketplace-with-royalties/contracts/managers/RoyaltiesManager.sol) The royalty will be 2.5%. The smart contracts still support the current fee for the DAO but is going to be 0%. I decided to keep it if for some reason we need to have something like 1% for the DAO and 1.5% for creators. The Grant amount can change. I've set a cap. I'm still waiting for the auditors' quote.
