license metadata remove path on top-down walk

Performance optimization means not every path will be traversed.

Instead of updating parents via the path, perform a 2nd bottom-up walk
after the top-down walk to propagate the new resolutions to parents.

Note: the 2nd walk method will add resolutions to statically linked
libraries etc. at deeper levels, but those do not affect what gets
reported. In particular, note that test data for dumpresolutions
changes, but none of the test data for listshare, checkshare etc.
changes.

Test: m all systemlicense listshare checkshare dumpgraph dumpresolutions
