[roll] Roll fuchsia [a11y] Simplify node skipping logic for linear navigation

GetNodesToExclude was sometimes not excluding enough nodes
(fxbug.dev/101948). This CL rebuilds it with a simpler approach.

Two differences from the original behavior:
1. We only make exclusion decisions based on a node and its parent, not
   its whole surrounding neighborhood.  This means that the 'linear
   motif' no longer has to end in a leaf node to be recognized.  I think
   this is a good simplification, but let me know if there's a case
   where this is important.
2. Previously, when entering a linear motif, we'd visit a different node
   when moving forwards vs. moving backwards. With this approach, we
   always visit the same node when entering the same linear motif. This
   is more visually consistent, which could benefit the sighted subset
   of screen reader users.

Integration

This repository contains Fuchsia's Global Integration manifest files.

Making changes

All changes should be made to the internal version of this repository. Our infrastructure automatically updates this version when the internal one changes.

Currently all changes must be made by a Google employee. Non-Google employees wishing to make a change can ask for assistance via the IRC channel #fuchsia on Freenode.

Obtaining the source

First install Jiri.

Next run:

$ jiri init
$ jiri import minimal https://fuchsia.googlesource.com/integration
$ jiri update

Third party

Third party projects should have their own subdirectory in ./third_party.
