fix: Extended UniversalRpcTests run times (#3560)

This PR condenses the total number of tests from roughly ~10k down to
~3.5k by grouping like test types and migrating all `[Values]` decorated
parameters to local properties.

**This helps to reduce:**
- The time spent setting up and tearing down a test for each unique
parameter value combination.
- The time spent starting and stopping NetworkManagers.
- The total number of tests is more than cut in half.
- _There is a known limitation with 2021 & 2022 TestRunner where
reaching/exceed the 8-10k total tests count range can start to impact
performance._

## Changelog

NA

## Testing and Documentation

- Includes some `UniversalRpcTests` refactoring.
- Includes new `UniversalRpcGroupedTests`.
- Includes commenting out all legacy tests that were migrated into
`UniversalRpcGroupedTests`.
