Revert "Include hidden objects in accessible tree."

This reverts commit 38084c4. Reason for revert: suspect of perf regression (crbug.com/1277867) Original change's description: > Include hidden objects in accessible tree. > > Include display:none, visibility:hidden and aria-hidden elements in > the accessible tree. > > We plan to use them to streamline the calculation of accessible names, > so it does not require additional DOM or layout tree traversals. We > previously attempted to include only those hidden nodes which were > required for accname calculation, but there were complications to > keep the tree up-to-date. This is much easier to maintain and it > doesn't seem to have a noticeable performance impact. > > A sizeable number of DumpAccessibilityTreeTest expectations were > updated to include the newly included hidden nodes. > > Original author was aleventhal@chromium.org in: > http://crrev.com/c/3197971 > > Bug: 1255036 > Change-Id: I899781b654dd2b1dd97473b92e26d95fa54376bc > Cq-Include-Trybots: luci.chromium.try:win7-blink-rel,win7-rel > Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/3217730 > Reviewed-by: Jonathan Ross <jonross@chromium.org> > Reviewed-by: Aaron Leventhal <aleventhal@chromium.org> > Reviewed-by: Nektarios Paisios <nektar@chromium.org> > Commit-Queue: Jacobo Aragunde Pérez <jaragunde@igalia.com> > Cr-Commit-Position: refs/heads/main@{#949376} Bug: 1255036, 1277867 Change-Id: I52ac49de456757114e706a0aaeabd0305899d6f6 Cq-Include-Trybots: luci.chromium.try:win7-blink-rel,win7-rel No-Presubmit: true No-Tree-Checks: true No-Try: true Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/3321548 Bot-Commit: Rubber Stamper <rubber-stamper@appspot.gserviceaccount.com> Reviewed-by: David Tseng <dtseng@chromium.org> Commit-Queue: Jacobo Aragunde Pérez <jaragunde@igalia.com> Cr-Commit-Position: refs/heads/main@{#949998}
