Reviewed by Aditya Keerthi.

Add a couple of new flags to `WebCore::NetworkConnectionIntegrity`, and expose it through new
corresponding SPI policy flags.

* Source/WebCore/PAL/pal/spi/cf/CFNetworkSPI.h:
* Source/WebCore/platform/network/NetworkConnectionIntegrity.h:
* Source/WebKit/NetworkProcess/cocoa/NetworkDataTaskCocoa.mm:
(WebKit::NetworkDataTaskCocoa::NetworkDataTaskCocoa):

Call `-_setWebSearchContent:` if the policy flag is set, and
`-[NSMutableURLRequest _setWebSearchContent:]` is available.
