This PR adds a new syntax for tactic and command configurations. It also
updates the elaborator construction command to be able to process this
new syntax.
We do not update core tactics yet. Once tactics switch over to it,
rather than (for example) writing `simp (config := { contextual := true,
maxSteps := 22})`, one can write `simp +contextual (maxSteps := 22)`.
The new syntax is reverse compatible in the sense that `(config := ...)`
still sets the entire configuration.
Note to metaprogrammers: Use `optConfig` instead of `(config)?`. The
elaborator generated by `declare_config_elab` accepts both old and new
configurations. The elaborator has also been written to be tolerant to
null nodes, so adapting to `optConfig` should be as easy as changing
just the syntax for your tactics and deleting `mkOptionalNode`.
Breaking change: The new system is mostly reverse compatible, however
the type of the generated elaborator now lands in `TacticM` to make use
of the current recovery state. Commands that wish to elaborate
configurations should now use `declare_command_config_elab` instead of
`declare_config_elab` to get an elaborator landing in `CommandElabM`.
