Revert "[Reland] Handle appearance value changes during <select> show…

…Picker."

This reverts commit 5fa283f55fea44480ce73308cb12de0274867c1e.

Reason for revert:
LUCI Bisection has identified this change as the cause of a test failure. See the analysis: https://ci.chromium.org/ui/p/chromium/bisection/test-analysis/b/5657193371140096

Sample build with failed test: https://ci.chromium.org/b/8726470617543936881
Affected test(s):
ninja://:blink_wpt_tests/external/wpt/html/semantics/forms/the-select-element/customizable-select/switch-picker-appearance.tentative.html

Original change's description:
> [Reland] Handle appearance value changes during <select> showPicker.
>
> When the appearance value changes as the result of the picker
> opening (e.g. via `::picker(select):open {appearance:auto}` or
> similar), we close the picker to avoid any oscillation or
> nonsensical behavior. This CL implements this change.
>
> The original CL [1] was reverted due to a strange bot failure [2]
> where the new set of promise_tests somehow fail because
> blink_wpt_tests is expecting an expectation file with a single blank
> line. I added a "Failure" expectation to hopefully avoid that, in
> Patchset 3.
