When reading this file, it is difficult to tell whether statements are about ordinal or natural powers; especially given that when leanprover/lean4#2220 is fixed the meanings may change. This adds type annotations to remove the ambiguity.
This folds in the changes from #8291

The commits above cherry-pick the changes from #8291 onto I did not directly merge #8291 as I did not want to pull in other changes from master and mess up Scott's automation setup. |

# PR contents This is the supremum of - #8284 - #8056 - #8023 - #8332 - #8226 (already approved) - #7834 (already approved) along with some minor fixes from failures on nightly-testing as Mathlib `master` is merged into it. Note that some PRs for changes that are already compatible with the current toolchain and will be necessary have already been split out: #8380. I am hopeful that in future we will be able to progressively merge adaptation PRs into a `bump/v4.X.0` branch, so we never end up with a "big merge" like this. However one of these adaptation PRs (#8056) predates my new scheme for combined CI, and it wasn't possible to keep that PR viable in the meantime. # Lean PRs involved in this bump In particular this includes adjustments for the Lean PRs * leanprover/lean4#2778 * leanprover/lean4#2790 * leanprover/lean4#2783 * leanprover/lean4#2825 * leanprover/lean4#2722 ## leanprover/lean4#2778 We can get rid of all the ``` local macro_rules | `($x ^ $y) => `(HPow.hPow $x $y) -- Porting note: See issue lean4#2220 ``` macros across Mathlib (and in any projects that want to write natural number powers of reals). ## leanprover/lean4#2722 Changes the default behaviour of `simp` to `(config := {decide := false})`. This makes `simp` (and consequentially `norm_num`) less powerful, but also more consistent, and less likely to blow up in long failures. This requires a variety of changes: changing some previously by `simp` or `norm_num` to `decide` or `rfl`, or adding `(config := {decide := true})`. ## leanprover/lean4#2783 This changed the behaviour of `simp` so that `simp [f]` will only unfold "fully applied" occurrences of `f`. The old behaviour can be recovered with `simp (config := { unfoldPartialApp := true })`. We may in future add a syntax for this, e.g. `simp [!f]`; please provide feedback! In the meantime, we have made the following changes: * switching to using explicit lemmas that have the intended level of application * `(config := { unfoldPartialApp := true })` in some places, to recover the old behaviour * Using `@[eqns]` to manually adjust the equation lemmas for a particular definition, recovering the old behaviour just for that definition. See #8371, where we do this for `Function.comp` and `Function.flip`. This change in Lean may require further changes down the line (e.g. adding the `!f` syntax, and/or upstreaming the special treatment for `Function.comp` and `Function.flip`, and/or removing this special treatment). Please keep an open and skeptical mind about these changes!
