This PR changes the elaboration of the `structure`/`class` commands so
that default values have later fields in context as well. This allows
field defaults to depend on fields that come both before and after them.
While this was already the case for inherited fields to some degree, it
now applies uniformly to all fields. Additionally, when elaborating the
default value for a field, all fields that depend on it are cleared from
the context to avoid situations where the default value depends on
itself.
This addresses an issue reported by Aaron Liu [on
Zulip](https://leanprover.zulipchat.com/#narrow/channel/270676-lean4/topic/default.20structure.20values.20can.20depend.20on.20themselves/near/578014370).
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.
