    Web Inspector: Incremental in FilterBar
    https://bugs.webkit.org/show_bug.cgi?id=260043

    Reviewed by Devin Rousso.

    The filter bar was not working correctly due to "search" being removed.

    Replace incremental with throttler. Delete incremental getter and setter.

    Switch eventlistener to "input" instead of "search".

    Rename "_handleFilterSearched" to "_handleFilterInput"

    Delete unused "_handleFilterInputEvent"
