Tagged rows and support for move outs in Electric DB collection (#942)

Builds on top of Electric's ts-client support for tagging rows and move out events: electric-sql/electric#3497

This PR extends tanstack DB such that it handles tagged rows and move out events. A tagged row is removed from the Electric collection when its tag set becomes empty. Note that rows only have tags when the shape they belong to has one or more subqueries.
