SystemUIService is hard-coded to dump at CRITICAL priority and so can't dump very much (and, most importantly, can't handle dumping our length log buffers). So instead we create a new service, SystemUIAuxiliaryDumpService, which will dump alongside all other services in the NORMAL section. Its dump method calls straight into the DumpManager. Test: atest, manual Change-Id: If76f206081a1663e23fc14076b50bef7396e517f
