Re-land r230914 (tab tooltip strings) with fix for generated_resources.grd issue, per joi@ and tony@.

It turns out adding strings to generated_resources.grd has caused us to reach our limit in the ID key space.  Per e-mail thread on chromium-dev@, we decided to make an ID bump in tools/gritsettings/resource_ids, to the starting point for webkit_strings.grd, in order to make room for more strings in generated_resources.grd.
