AMD VIP agent abstractization

[IstvanZsSzekely]

PR Description

VIP agents AMD are parameterized are all parameterized agents and they don't have an abstract parent class. This forces us to use Environments which are also parameterized, so the AMD agents can be instantiated inside the environment.
The ADI VIP classes encapsulate the AMD VIPs, which allows us to create VIP agents in a cleaner way, including our own sequencers and monitors, but these are also parameterized. Our VIP classes have an abstract parent class, which means polymorphism works on them.
This PR adds a workaround for this issue to have an abstract, polymorphic environment, that can use VIPs in multiple modes without the need of redefining the entire environment multiple times with different modes. This polymorphic attribute is set at environment creation, which gives a seamless plug-and-play feature when multiple environments need to be connected for a more comprehensive system level testbenches.
