make query_group macro procedural
...
Switch to a procedural implementation of the `query_group!` macro,
residing in the `components/salsa_macros` subcrate.
Allow the user to override the invoked function via `salsa::invoke(...)`
and the name of the generated query type via `salsa::query_type(...)`.
In all tests, replace the `salsa::query_group! { ... }` invocations with
the new attribute-style `#[salsa::query_group]` macro, and change them
to the new naming scheme for query types (`...Query`).
Update README, examples, and documentation.

prevent untracked queries from moving brackwards in time
...
If a query observes an untracked read, it gets changed_at equal to the
current revision. When we re-validate the query later, if it doesn't
do an untracked read this time, it gets changed_at equal to the
maximum of the dependencies. Crucially, this new changed_at may
be **older** then the previous value of changed_at. That is, we break
the rule that `changed_at` monotonically increases.
This can lead to missed re-executions down the line (see the added
test).

Using two snapshots from the same thread isn't really very easy to do,
so we don't have to warn about that really (it's really nested use of
snapshots that's a problem, and to do that you have to use thread-locals
or something just to get the snapshot *into* the database -- at that
point, something is really going wrong)).

their state.
