Remove ::select-fallback-button

This patch removes customizable \<select>'s fallback \<button> element in
the UA shadowroot by replacing it with the same "InnerElement" \<div>
which is used for appearance:auto.

Several supporting changes were made in order to implement this:

• Also remove ::select-fallback-button-text
• Add -internal-appearance-auto-base-select() support for the following
  properties:
  • min-block-size
  • min-inline-size
  • padding-block-start
  • padding-block-end
  • padding-inline-start
  • padding-inline-end
  • content in select::after
• Make \<select> focusable again when there is no child \<button> element
• Remove dependency on popover triggering code in HTMLFormControlElement
  now that we aren't always opening the popover with a \<button>

This is in response to feedback here:
https://github.com/w3c/csswg-drafts/issues/10717

This also addresses additional feedback I received privately that author
styles applied to the select element itself weren't applying to the
in-page portion of the element.
