 In this file we characterise the interaction of `upper_set`/`lower_set` and `locally_finite_order`.

chore: Move intervals (#11765)

Move Set.Ixx, Finset.Ixx, Multiset.Ixx together under two different folders:

Order.Interval for their definition and basic properties
Algebra.Order.Interval for their algebraic properties

Move the definitions of Multiset.Ixx to what is now Order.Interval.Multiset. I believe we could just delete this file in a later PR as nothing uses it (and I already had doubts when defining Multiset.Ixx three years ago).

Move the algebraic results out of what is now Order.Interval.Finset.Basic to a new file Algebra.Order.Interval.Finset.Basic.

chore: banish Type _ and Sort _ (#6499)

We remove all possible occurences of Type _ and Sort _ in favor of Type* and Sort*.

This has nice performance benefits.
