fix: process delayed assignment metavariables correctly in Lean.Meta.Closure (#6414) 
This PR fixes a bug in `Lean.Meta.Closure` that would introduce
under-applied delayed assignment metavariables, which would keep them
from ever getting instantiated. This bug affected `match` elaboration
when the expected type contained postponed elaboration problems, for
example tactic blocks.

Closes #5925, closes #6354

feat: Nat.(fold|foldRev|any|all)M? take a function which sees the upper bound (#6139) 
This PR modifies the signature of the functions `Nat.fold`,
`Nat.foldRev`, `Nat.any`, `Nat.all`, so that the function is passed the
upper bound. This allows us to change runtime array bounds checks to
compile time checks in many places.

feat: change Array.get to take a Nat and a proof (#6032) 
This PR changes the signature of `Array.get` to take a Nat and a proof,
rather than a `Fin`, for consistency with the rest of the (planned)
Array API. Note that because of bootstrapping issues we can't provide
`get_elem_tactic` as an autoparameter for the proof. As users will
mostly use the `xs[i]` notation provided by `GetElem`, this hopefully
isn't a problem.

We may restore `Fin` based versions, either here or downstream, as
needed, but they won't be the "main" functions.

feat: change Array.set to take a Nat and a tactic provided bound (#5988) 
This PR changes the signature of `Array.set` to take a `Nat`, and a
tactic-provided bound, rather than a `Fin`.

Corresponding changes (but without the auto-param) for `Array.get` will
arrive shortly, after which I'll go more pervasively through the Array
API.

refactor: port mk_definition_inferring_unsafe to Lean (#4498) 
this already can be used in two places, and will be used more as I port
more constructions. Hope the location in `Lean.Environment` is ok.

d6f778bec4 refactor: arbitrary without explicit arguments 
@Kha I was tired of writing `arbitrary _` :)
There 0 places in the stdlib where the type needs to be provided.
If in the future we need to specify the type we can use
`arbitrary (α := <type>)`

a04fc631e0 doc: Closure.lean 
@Kha I documented the new `Closure.lean` module, and tried to capture
the issues we discussed this morning.
Tomorrow, I will implement a similar procedure for "closing" all the
let-recs in a `mutual` block.
