CSP: group policies in didAddContentSecurityPolicy.
This CL makes chrome sends one IPC in
ContentSecurityPolicy::reportAccumulatedHeaders instead
of one IPC per CSP headers.
In addition, in didAddContentSecurityPolicy, the CSP header
is no more sent since it is already included in the parsed
policy.
