Added fix to allow getroothash to work with no api running (erigontec…

…h#8342)

Whitelisting calculation of the roothash should not be dependent on the
bor api running. This will not always be the case, for example when
erigon is configured with a separate rpc deamon.

To fix this the calculation has been moved to Bor.

Additionally the redundant Bor API code has been removed as this is not
called by any code and the functionality looks to have migrated to the
turbo/jsonrpc package.
