This reverts commit 4c094342.

Reason for revert: Unfortunately this broke all perf builders.

Original change's description:
> [test] Add logic to run tests on Android
> 
> This adds a new command abstraction for running commands on Android
> using dockered devices on swarming.
> 
> The new abstraction handles pushing all required files to the device.
> The logic used for pushing and running is reused from the perf runner.
> 
> This adds only the mjsunit test suite. Others will be handled in
> follow up CLs. The suite logic is enhanced with auto-detection of files
> to be pushed to devices, for e.g. load or import statements.
> 
> Some test cases need an extra resource section for specifying required
> files.
> 
> Remaining failing tests are marked in the status files for later
> triage.
> 
> Bug: chromium:866862
