fix: select combo box input text on next click after dropdown closed

[ugur-vaadin]

Description

Outside click on combo box does not make it lose focus. However, since the selection of input text happens on focus (see input-control-mixin), this prevents autoselect from selecting the input text on click again. This PR makes the combo box select the input text on click once after dropdown closed if the combo box is autoselect.

Fixes #11188

Updated the PR to handle the case where user selects text manually after outside click. Now, before selecting the text on click, we check if the input text is already selected (partially or fully). If there is a selection, the autoselect does not lead to selecting the whole text in order to avoid interfering with the user's intent.
