note: if you ever have java files that will be different for shell vs webvr,
it'd be better to just inline them here rather than have this
chrome_vr_java_sources variable.

We are expecting to ship webvr and vr shell at M56. And once shipped,
does it mean we will need to move these files back to  java_sources.gni
like other java files. If this is the case, I would prefer to keep it this way
for now if you don't mind.
