This restores support for versions of the inpage provider prior to v8. This is intended to support dapps and extensions that directly instantiated their own provider rather than using the injected provider. * Forward traffic between old and new provider streams * Ignore publicConfig stream for non-legacy muxes * Transform accountsChanged notification for legacy streams * Convert publicConfigStore to singleton Co-authored-by: Mark Stacey <markjstacey@gmail.com>
