Per the CSP specification, content injected by extensions is meant to be exempt from page CSP. This patch takes care of the most common case of content injected by extension content scripts, which always have expanded principals which inherit from the page principal. To make this easier, de-virtualize BasePrincipal::Kind(), using CTOR initializers instead.
