This CL marks (on Android) the android-app scheme as hierarchical
("standard") in order for them to not get butchered by "truncate to
origin" referrer policies, such as the new default policy (currently
in the process of rolling out; crbug.com/1014207) of
strict-origin-when-cross-origin.

URLs of the android-app scheme are of the form
android-app://my.package.name/some/more/information; because they're not
"standard" (GURL) / "hierarchical" (KURL), when you take their origin
you get an opaque origin; because they're cross-origin with everything
else, a policy of "truncate to origin on cross-origin requests" (which
is the new default) ends up zeroing these referrers out, which might
not be what we want.

Marking the scheme as standard means that you can meaningfully take
the origin (usually yielding the package name), which gives the behavior
we want.
