[e2e CI] Refactor e2e CI tests to make addition of new tests easier

-- Currently there are lot of repeated codes which makes :-
   1. Maintaining the codebase
   2. Addition of new tests
   quite cumbersome.
-- Since most tests are bound to go through a certain lowering pipeline,
   decide whether or not to use ukernel, chess, have additional compilation
   flags - it's better to separate those as RunningParams instances.
-- This way they're handled unanimously at the base class instead of each
   subclass.
-- This can further be refined but for now going ahead with the current
   design.
