Enable/disable hardware rendering on windows by application tag

Previously, hardware rendering cannot be enabled or disabled
on windows created without a parent activity (e.g. by services)
by setting the <application> tag, "android:hardwareAccelerated"
in AndroidManifest.xml. It's enabled by default in Android L
from the commit, 5e1565ead6dbb7d5c414522591f61b16a23de1c3.
This patch provides a way of setting hardware rendering for
that case.
