Allow fallback to hdpi assets when mdpi is missing

Google has deprecated MDPI in AOSP as no Nexus devices
have that density any more.  As a result, there are
an increasing number of missing assets in the tree
for this density.  This causes SystemUI to crash.

This allows HDPI assets to be used as a fallback
for MDPI assets that are not present.
