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.

# Structure copied parents should be able to refer to other parents as instances

Issue: https://github.com/leanprover/lean4/issues/2611

Example that worked before the fixes for 2611. The projection `D.toC` refers to `D.toA` for the `A` instance.
|
||
This is a natural consequence to the way subobject projection functions are added by `mkProjections`.

class A
|
||
class C [A]
|
||
class D extends A, C
|
||
|
||
/-!
|
||
This example did not work. Since `C` provides a `B` field, it's a copied parent.
|
||
Now there is a step where the fvar for the `A` instance is replaced by the `D.toA` constant.

A test that this still works even when there are parameters on the structure.
