[Extensions Click-to-Script] Adjust icon grayscaling behavior

Currently, extension icons in the toolbar are grayscaled when the
extension action (i.e., the page action or the browser action) is
disabled. However, this can be confusing, because it makes the extension
look disabled when it might be running on that page.

With runtime host permissions enabled, the extension icon should only be
grayscaled in the toolbar only if the action is currently disabled *and*
the extension cannot currently inject on the page. This addresses the
confusing "disabled" look, as well as preventing the strange case of
"clicking on the extension icon and it immediately becoming disabled."

[jumbo] avoid ambiguities between extensions::features:: and features::

extensions/common/extension_features.h contains an extensions::features
namespace, which can be confused with chrome/common/chrome_features.h's
features namespace in jumbo builds.

Let's disambiguate these enough to get jumbo builds working again.

Followup to this CL, which uncovered the issue (but didn't cause it):

[Extensions Click-to-Script] Fix grayscaling with content script access

With runtime host permissions, extension icons shouldn't be grayscaled
when they have access to the page. Correctly account for content script
permissions in this checking, and add unittests for the same.
