[Context menu redesign] Display URLs always LTR

Forcing it to LTR makes sure the URL is not shown out-of-order when
the first strong character of the URL is RTL.

This CL also updates the RevampedContextMenuHeaderMediator's
constructor to have a ContextMenuParams parameter instead of several
parameters that are possible to extract from the ContextMenuParams.
