[subresource_filter] Properly handle blank/data/srdoc navigation activation

It is relatively common to load resources in subframes that navigate
but do not trigger ReadyToCommitNavigation in the browser process,
or go through the standard NavigationThrottle pipeline.

Previously, the component explicitly ignored them since their loads do
not align well with our navigation/browser oriented architecture.

This CL simply forwards the parent frame's activation state into the
child, which the child uses any time it navigates to one of these
special URLs.

[subresource filter] Adds support for PlzNavigate for special urls handling.

Since special urls like about:blank, about:srcdoc etc. do not lead to
creation of navigation throttles, subresource filter's code treats 
such sub-frames specially in the renderer code. This CL will align the
triggering condition for these special urls with how PlzNavigate decides
a URL to be special.

This CL does the following:
- Moves ShouldUseParentNavigation to content/common so that it could be
used by browser side code.
- Branches ShouldUseParentNavigation to use ShouldMakeNetworkRequestForURL
for PlzNavigate. This will have the functional change that data url will go
through navigation throttles. This also required moving
ShouldMakeNetworkRequestForURL to content/public/common.
- Makes sure DidCommitProvisionalLoad at renderer side does not early
return for PlzNavigate Data url scenario by modifying the early return
condition.

[subresource filter] Persists browser side activation state for special url sub-frames.

Special url schemes that do not require a network request, do not go through
creating navigation throttles. Such iframes therefore do not get to compute their
activation state. For renderer initiated navigations, in renderer they inherit the 
activation state of their parent in DidCommitProvisionalLoad so that any sub-resources 
they load can be checked for blocking.
This CL does the same for them in the browser process in DidFinishNavigation so that
any of their normal-url child iframes can be activated as well. 

The impact of this CL is that it will increase the coverage of subresource filtering
to include child frames of special url frames.
