Revert 202215 "Migrate the IndexedDB backend from Blink to Chromium"

> Migrate the IndexedDB backend from Blink to Chromium
>
> To get the IDB backend off the (deprecated) WebKit thread, remove
> intermediate proxying, and let us take advantage of base utilities,
> we're moving the code from Blink to Chromium.
>
> This patch is basically a glorified copy/paste of the Blink IDB
> backend code, with Chromium coding style applied, WTF dependencies
> replaced with STL and base/, redundant classes removed, etc. It
> introduces some new temporary proxy classes
> (content/browser/webidb*_impl.*) to allow us build both the old and
> new backends.
>
> The new backend is currently disabled by default. It can be enabled
> using a new (and temporary) command line switch: --new-indexeddb Once
> we've done some further cleanup and are confident that the new backend
> is stable, and the bots have moved from DumpRenderTree to
> content_shell, we'll switch to the new backend by default. Once that
> has survived through a dev channel release, we'll delete the Blink
> code and eliminate unnecessary proxy classes.
