  [MemProf] Simplify edge iterations (NFC) (#123469)

Remove edge iterator parameters from the various helpers that move edges
onto other nodes, and their associated iterator update code, and instead
iterate over copies of the edge lists in the caller loops. This also
avoids the need to increment these iterators at every early loop
continue.

This simplifies the code, makes it less error prone when updating, and
in particular, facilitates adding handling of recursive contexts.

There were no measurable compile time and memory overhead effects for a
large target.
