Replace base-select svg with disclosure-open
This was suggested here:
w3c/csswg-drafts#10380 (comment)
This patch also adds min-inline-size and min-block-size to
::select-fallback-button because changing the icon caused the total size
of the button to decrease which revealed the lack of min sizing which is
already tested by
select-accessibility-minimum-target-size.tentative.html
The UA select:open rules caused a performance regression for large
s because it caused a style recalc immediately after opening the
appearance:auto picker which in re-serializes all of the data for the
popup and sends it to the popup, which is very slow for large selects. I
addressed this by starting to match :open before creating the popup in
MenuListSelectType::ShowPopup.
