This PR reviews the implicitness of arguments across List/Array/Vector,
generally trying to make arguments implicit where possible, although
sometimes correcting propositional arguments which were incorrectly
implicit to explicit.
This PR provides lemmas for the tree map function `maxKey?` and its
interations with other functions for which lemmas already exist.

This PR add missing lemmas about the tree map: `minKey*` variants return
the head of `keys`, `keys` and `toList` are ordered and `getKey*
t.minKey?` equals the minimum.

There are several things done here:
1. Use the modified `simp_to_model` which already exists in hash maps.
This version of `simp_to_model` allows specifying the query operations
to use in addition to the modifying operations. This is mostly to
improve elaboration time and actually increases olean size.
2. Instead of proving `toListModel_balance` directly, we write
`toListModel_balanceₘ` and use that instead (this saves ~3 MB).
3. Use `fun_cases` and `dsimp` instead of `rw [x.eq_def]` more
frequently in `Balancing.olean` (this saves a bit over 2 MB).
4. Mark `updateCell` and other functions dependent on it as
`noncomputable`. The main problem with `updateCell` is how other
functions, in particular `glue`, get recursively inlined, which blows
the size of the IR (this saves ~1 MB).
5. Instead of using `simp_to_model` to prove results on `insert!`,
`erase!`, etc., `simpa`s are used now, e.g. `simpa only
[insert_eq_insert!] using isEmpty_insert h`. This mainly improves
elaboration time although the olean size also goes down by ~0.3 MB.
This PR provides lemmas about the tree map that have been introduced to
the hash map in #7289.

This PR renames the member `insert_emptyc_eq` of the `LawfulSingleton`
typeclass to `insert_empty_eq` to conform to the recommended spelling of
`∅` as `empty`.
See also #7447.
This PR provides lemmas about the tree map function `modify` and its
interactions with other functions for which lemmas already exist.

This PR provides lemmas for the tree map functions `alter` and `modify`
and their interactions with other functions for which lemmas already
exist.
BREAKING CHANGE: The signature of `size_alter` was corrected for all
four hash map types. Instead of relying on the boolean operations
`contains` and `&&` in the if statements, we now use the `Prop`-based
operations `Membership` and `And`.

lemmas about `ofList`, which is related to `insertMany`, are not
included.

This PR provides lemmas about the tree map functions `foldlM`, `foldl`,
`foldrM` and `foldr` and their interactions with other functions for
which lemmas already exist. Additionally, it generalizes the
`fold*`/`keys` lemmas to arbitrary tree maps, which were previously
stated only for the `DTreeMap α Unit` case.
A later PR will make the hash map functions `fold` and `revFold`
internal and also update their signature to conform to the tree map and
list API. This is out of scope for this PR.

This PR changes the order of arguments of the folding function expected
by the tree map's `foldr` and `foldrM` functions so that they are
consistent with the API of `List`.

This PR provides lemmas about the tree map functions `keys` and `toList`

is fixed.

This PR provides proofs that the raw tree map operations are well-formed
and refactors the file structure of the tree map, introducing new
modules `Std.{DTreeMap,TreeMap,TreeSet}.Raw` and splittting
`AdditionalOperations` into separate files for bundled and raw types.

This PR provides lemmas for the tree map functions `get`, `get!` and
`getD` in relation to the other operations for which lemmas already
exist.
Internally, the `simp_to_model` tactic was provided two new simp lemmas
to eliminate some common complications that require `rw`'ing before
using `simp_to_model`. However, it is still necessary to sometimes
`revert` some hypotheses.

This PR removes the `simp` attribute from `ReflCmp.compare_self` because
it matches arbitrary function applications. Instead, a new `simp` lemma
`ReflOrd.compare_self` is introduced, which only matches applications of
`compare`.

This PR implements the methods `min`, `max`, `minKey`, `maxKey`,
`atIndex`, `getEntryLE`, `getKeyLE` and consorts on the tree map.
In order to implement the proof-based functions such as `min` and
`getEntryLT` in `Queries.lean`, it was necessary to extract `Balanced`
and `Ordered` into new files so that they can be used from
`Queries.lean`.

This PR introduces ordered map data structures, namely `DTreeMap`,
`TreeMap`, `TreeSet` and their `.Raw` variants, into the standard
library. There are still some operations missing that the hash map has.
As of now, the operations are unverified, but the corresponding lemmas
will follow in subsequent PRs. While the tree map has already been
optimized, more micro-optimization will follow as soon as the new code
generator is ready.
