Shuffle jobs off Nexus5x.

All Golo devices except 2 are AWOL. We added 6 to the Skolo, but they
can't keep up.

This CL moves the following jobs off Nexus5x:
 - All ASAN jobs to Pixel. Most other devices we have can't be rooted,
   so they can't run ASAN.
 - Vulkan NoGPUThreads arm64 jobs to NVIDIA_Shield. Of the devices that
   support Vulkan, this has the most available capacity.
    - I removed the arm32 Vulkan NoGPUThreads jobs because it seems a
      bit esoteric.
    - Also removed arm32 Vulkan Debug Perf because I can't imagine it
      would ever give us info that arm64 doesn't already provide. (We
      ignore Perf data from Debug builds.)
    - Other arm32 Vulkan jobs stayed on Nexus5x because we don't have
      any other Vulkan-capable devices with spare capacity.
 - Most arm32 jobs to MotoG4 and de-duplicated. This device has an
   ARMv8 processor but runs everything in arm32 mode, which is exactly
   what these jobs are trying to test. We have a bunch of MotoG4s in
   the Skolo; however, they don't support Vulkan or ASAN.
 - NoGPUThreads and NativeFonts arm64 jobs to GalaxyS6. There are only
   6 in the Skolo, but for some reason these devices are particularly
   fast. They also don't support Vulkan or ASAN.
    - Currently GalaxyS6 CPU arm64 jobs fail, possibly due to OOM. I
      will try to move those jobs in a future CL.
