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.

# Test for issue #11690: grind should support dot notation on declarations
When using `grind only [foo.le]` where `foo.le` is dot notation applying
`LT.lt.le` to a theorem `foo`, grind should elaborate it as a term rather
than failing with "Unknown constant `foo.le`".

class Preorder (α : Type) extends LE α, LT α where
theorem le_of_lt [Preorder α] {a b : α} (hab : a < b) : a ≤ b := sorry
variable [Preorder α]
