Otherwise it gets a different value when using starlark
board config, causing the ninja files to differ.

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.

Soong will use this to turn on universal binary support (X86_64 + Arm64
in the same binary).

(cherry picked from commit 33fc244de5)
Tune the top-down walk to avoid needlessly walking the same subtree
over and over again with the same condition(s).
Takes walking system image down from 3m to 1.5s.

Test: Full/Incremental OTA tested on CF, Pixel
OTA Merge time performance on Pixel (bramble)

1: VAB - Compression with dm-snapshot (on Android S)
Merge-time = 344 seconds (~5.7 minutes)
2: VAB - Compression with user-snapshot (on Android T)
Merge-time = 53 seconds
3: VAB - Without compression (using kernel COW format)
Merge-time = 33 seconds
Compared to Android S, merge time improves by 84% with user-snapshots on Android T.
The 20 seconds difference between (2) and (3) is because of two phase merge during compression which essentially serializes merge start time between partitions.
On (3), there is no two phase merge as all the partition starts merge at the same time.
When there is no two phase merge involved, (2) and (3) are nearly identical.
============================================================
Full OTA - 1.8G
1: VAB - Compression with dm-snapshot (on Android S)
Merge-time = 40 seconds
2: VAB - Compression with user-snapshot (on Android T)
Merge-time = 32 seconds
3: VAB - Without compression (using kernel COW format)
Merge-time = 32 seconds
===============================================================
Presubmit OTA testing enabled on Cuttlefish for ~1 Week with
the feature enabled.
