chore: switch to new test/bench suite (#12590)
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.

/- In the following example, type of `x` and `y` could be any type `α` s.t. `[OfNat α]`.
It relies on `SyntheticMVarKind.withDefault` to set `α := Nat`.
Moreover, we must commit to `α := Nat` before we try to build de `matcher` since
`mkMatcher` assumes `matchType` does not contain metavariables.
We accomplish that by invoking `synthesizeSyntheticMVarsNoPostponing` at `elabMatch`. -/
