This PR is followup to the change in grind pattern heuristics from
#10342, typically resolving the discrepancy by writing out an explicit
`grind_pattern` for the intended pattern. The new behaviour is more
aggressive, because it selects smaller patterns.
This PR completes the review of `@[grind]` annotations without a sigil
(e.g. `=` or `←`), replacing most of them with more specific annotations
or patterns.

This PR adds missing the lemmas `ofList_eq_insertMany_empty`,
`get?_eq_some_iff`, `getElem?_eq_some_iff` and `getKey?_eq_some_iff` to
all container types.
This PR makes `IsPreorder`, `IsPartialOrder`, `IsLinearPreorder` and
`IsLinearOrder` extend `BEq` and `Ord` as appropriate, adds the
`LawfulOrderBEq` and `LawfulOrderOrd` typeclasses relating `BEq` and
`Ord` to `LE`, and adds many lemmas and instances.
Note: This PR contains a refactoring where `Init.Data.Ord` is moved to
`Init.Data.Ord.Basic`. If I added `Init.Data.Ord` simply importing all
submodules, git would not be able to determine that `Init.Data.Ord` was
renamed to `Init.Data.Ord.Basic`. This could lead to unnecessary merge
conflicts in the future. Hence, I chose the name `Init.Data.OrdRoot`
instead of `Init.Data.Ord` temporarily. After this PR, I will rename
this module back to `Init.Data.Ord` in a separate PR.
(This is a copy of #9430: I will not touch that PR because it currently
allows to debug a CI problem and pushing commits might break the
reproducibility.)
This PR adds lemmas for the `TreeMap` operations `filter`, `map` and
`filterMap`. These lemmas existed already for hash maps and are simply
ported over from there.
This PR adds the types `Std.ExtDTreeMap`, `Std.ExtTreeMap` and
`Std.ExtTreeSet` of extensional tree maps and sets. These are very
similar in construction to the existing extensional hash maps with one
exception: extensional tree maps and sets provide all functions from
regular tree maps and sets. This is possible because in contrast to hash
maps, tree maps are always ordered.
This PR adds an equivalence relation to tree maps akin to the existing
one for hash maps. In order to get many congruence lemmas to eventually
use for defining functions on extensional tree maps, almost all of the
remaining tree map functions have also been given lemmas to relate them
to list functions, although these aren't currently used to prove lemmas
other than congruence lemmas.
This PR adjusts the grind annotation on
`Std.HashMap.map_fst_toList_eq_keys` and variants, so `grind` can reason
bidirectionally between `m.keys` and `m.toList`.
This PR adds unconditional lemmas for
`HashMap.getElem?_insertMany_list`, alongside the existing ones that
have quite strong preconditions. Also for TreeMap (and
dependent/extensional variants).
This PR introduces the modules `Std.Data.DTreeMap.Raw`,
`Std.Data.TreeMap.Raw` and `Std.Data.TreeSet.Raw` and imports them into
`Std.Data`. All modules related to the raw tree maps are imported into
these new modules so that they are now a transitive dependency of `Std`.
This PR is a follow-up to #7695, which removed `simp` attributes from
tree map lemmas with bad discrimination patterns. In this PR, we
introduce some `Ord`-based lemmas that are more simp-friendly.

the head of `keys`, `keys` and `toList` are ordered and `getKey*
t.minKey?` equals the minimum.

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`.

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`.

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 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.
