Robert Phillips d6cf56fd34 Revert "[svg] Relocate out of experimental"
This reverts commit 6fc4106a9d.

Reason for revert: Blocking the Android roll

Original change's description:
> [svg] Relocate out of experimental
>
> Move the SVG rendering code to modules/svg, and componentize.
> Also split into include/src/utils.
>
> As external clients still reference the old header locations,
> introduce temporary forwarding headers to facilitate the migration.
>
