[ML] Single metric viewer: Fixes full page refresh behavior. (elastic…

…#44884) Fixes the behavior where a refresh triggered by timefilter would completely reload the page and e.g. reset the visibility and state of the Create rules flyout. The refresh() method now features a fullRefresh flag which defaults to the previous behaviour of a full reload. A full reload still gets triggered e.g. if a user changes the selection in one of the detector or entity dropdowns. A 'soft' refresh using fullRefresh=false is used if timefilter triggers a refresh. To be able to indicate that a 'soft' refresh is going on, a full-width progress bar was added below the tab menu item's horizontal line.
