Utilize TestContentClient in RenderViewTest as resources are being migrated to using grd system.

Utilize TestContentClient in RenderViewTest as resources are being migrated to using grd system.

Blink is about to use blink_resources.grd for the inline resources of user agent stylesheets.
This removes the dependency upon using make-file-arrays.py which embeds these resources as strings.

This patch instantiates TestContentClient which does all the plumbing required for various test targets in content.
As the resources are being moved into blink_resources.grd, this generates blink_resources.pak.
This pak doesn't exists as a separate pak file but its repacked into "content_shell.pak".

This blink side changes were reverted here https://codereview.chromium.org/567073004/

The reason for reverting: Breaking quite a few browser_tests and content_browsertests across multiple platforms.
