Bug 1916774 [wpt PR 47965] - Require ::picker(select) appearance:base-select opt-in, a=testonly

Automatic update from web-platform-tests
Require ::picker(select) appearance:base-select opt-in

This patch requires that not only appearance:base-select be applied to
<select> to make the popup be a popover, but also for
appearance:base-select to be applied to select::picker(select). This is
being discussed here: w3c/csswg-drafts#10440
