[kernel][vm] Simplify traversal return code handling

The ForEveryPageAndContiguousRunInRange helper in turn calls
ForEveryPageAndGapInRange, supplying it with a per-page function and a
gap function. ForEveryPageAndGapInRange is capable of handling
ZX_ERR_STOP in these functions correctly, so we do not need to handle
it in the page and gap functions used here.

Also fixes a bug where contiguous_run_len would not get reset to 0 in
the case of early termination due to ZX_ERR_STOP, invoking
contiguous_run_func on the last range twice. The added test case covers
this.
