This PR sets up the new integrated test/bench suite. It then migrates all benchmarks and some related tests to the new suite. There's also some documentation and some linting. For now, a lot of the old tests are left alone so this PR doesn't become even larger than it already is. Eventually, all tests should be migrated to the new suite though so there isn't a confusing mix of two systems.

The type of `x` is unfolded to find `Set.union`

Since the types are defeq, this alias works:

|

example (x y : FinSet 10) : FinSet 10 :=
|

FinSet.union x y
|

|

/-!
|
||
However, this dot notation fails since there is no `FinSet` argument.
|
||
However, unfolding is the preferred method.

error: Invalid field notation: Function `Set.union` does not have a usable parameter of type `FinSet ...` for which to substitute `x`
|
||
|
||
Note: Such a parameter must be explicit, or implicit with a unique name, to be used by field notation
