Add and enforce maxPrice parameter when minting tokens

[Ramarti]

Description and context

As reported by Trust sec, mintLicense() could be frontrun by the seller changing the licensing terms to a higher price than the buyer is expecting.

Suggested solution

Adding a maxPrice parameter as user input in mintLicenseTokens, similar to how AMMs allows the user to set slippage limits to protect against fluctuations in price.

To be able to enforce it, ERC20 transfers must happen at the LicensingModule level, Royalty Policies must return the price instead.

Definition of done

Scenario tested, code merged and deployed.
