CSP: Remove 'plugin-types' directive

The Content Security Policy directive 'plugin-types' is being removed
by the specification
(w3c/webappsec-csp#456). This CL removes the
code parsing and checking the 'plugin-types' directive from Blink and
from the services/network CSP parser. All WP tests for plugin-types
are removed, too.

When parsing a plugin-types directive, we display a console error
message informing that the directive has been removed and that
object-src can be used instead.
