Tyler Denniston 14d64afaa8 Revert "Initial checkin of GM verifier framework" 
This reverts commit 7e36f0015e.

Reason for revert: breaking google3 roll

Original change's description:
> Initial checkin of GM verifier framework
> 
> The goal of the verifier framework is to enable opt-in checks of the
> images produced by individual GMs. The basis of verification will be
> comparing the rendered output of a GM against a source-of-truth image,
> such as one generated by the CPU backend.
> 
> In the short term this can enable coarse-grained sanity checks for a
> subset of GMs to catch e.g. egregious rendering bugs. In the longer term
> this can provide an SkQP-style suite of tests that can be run across
> many/all GMs to provide a vote of confidence in the rendering
> correctness of new devices.
> 
> Bug: skia:9855
