[SelectMenu] Allow the UA provided shadow DOM to be replaced via attachShadow.

This CL enables authors to replace the UA provided shadow DOM
for \<selectmenu> by calling attachShadow().

For now this change follows the behavior of declarative shadow DOM
where the initial shadow DOM is emptied out and attachShadow returns
a reference to it. There is an open-ui issue1 to further discuss this
behavior.

The initial properties of the UA shadow root are updated with
the ones provided by attachShadow.
