we need to sort types in a [with] because the order comes from iterating a TypeHash, which is nondeterministic (specifically, the order is different if we disable stack allocation) and brittle. Unfortunately, we lack a good comparison for types, so as a hacky workaround here we format to a string (actually, a string list for easier line breaking when pretty printing) and sort lexicographically before finally printing.

Reconstruct a more faithful representation of
with-kinds when constructing outcome jkinds fromJkind.ts, using constant modalities on axes to omit types from axes which don't have those types in their baggage.This approach is pretty dumb (we just walk the baggage of each axis building up a map tracking which types are mentioned on which axes), but from reading the existing test cases it seems to do a pretty good job of constructing the jkind that the user would have written down themselves - plus it's vastly better than the previous approach of just printing a kind that wouldn't even parse, let alone be correct.
Plausibly this approach would need to be rethought completely once we introduce non-constant/identity modalities, but those are far enough off that I claim this should serve us fine for the time being.
Review the whole diff, rather than individual commits.
