Allow parameterization of tests across a predefined array of values

Describe the feature you would like

It'd be great if the user was able to run a test or even a whole collection of tests across a chosen set of input values.
(Note that this is different from fuzz testing across random values).

Example use cases:

• Run tests across different address inputs. (Different Token Addresses, Contract Owner vs. non-owner, Contract vs. EOA etc)
• Run a set of tests both before and after the upgrade of a contract

The feature would ideally allow the user to:

• Parameterize a single test
• Parameterize a whole test collection (contract)
• Specify multiple parameters in which case the test(-collection) will be run for all combinations
• Set the values to parameterize dynamically (for example in the setUp method) (optional)
• Pass filter arguments to forge test to only run a subset of the originally specified parameter space (similar to --match-test

Additional context

One testing library that does this fairly well imo is pytest (see here).

I'd argue this is a duplicate of #858, so I'm closing this as such - please let me know if the feature outlined in #858 is not the same as this 😄
