Disable Android benchmarks while device is offline. (iree-org#17910)

We have two pixel-6-pro devices/runners, one labeled for `presubmit` one
labeled for `postsubmit`. The presubmit runner has been offline for
multiple days, causing benchmark runs on LLVM integrate PRs to time out
waiting for a runner (and blocking other benchmark results from getting
reported as PR comments).

Some options:
* iree-org#17896 
* Switch only Android presubmit benchmarks to also use postsubmit
benchmark runners
* Turn off Android benchmarks on presubmit (or just for LLVM integrate
PRs)
* Switch benchmarks from pixel-6-pro to pixel-8-pro (we tried this
before but pixel 6 was more stable than pixel 8... I'm not sure how much
that level of stability is useful at this stage though, need to keep
rolling forward with testing on recent hardware)
* (THIS PR) Turn off Android benchmarks entirely
