[compiler][be] Stabilize compiler output: sort deps and decls by name (#31362)

All dependencies and declarations of a reactive scope can be reordered
to scope start/end. i.e. generated code does not depend on conditional
short-circuiting logic as dependencies are inferred to have no side
effects.

Sorting these by name helps us get higher signal compilation snapshot
diffs when upgrading the compiler and testing PRs
