Hey guys,

In findit we had android_chromium_variable taking care of more try job types
than it should have (not all were compatible such as Android GN), so this change
separates out variable builders to handle the different types properly. PTAL
when you have the chance.

Thanks,
Jeff

LGTM both code and capacity: https://goto.google.com/xegfr

In particular, I was worried about the disk space for the new builders, but all
slaves in this pool still run at ~10% disk capacity (check out the new disk
graph!), so we should be OK.
