Disable VP9.2 hw decoding on AMD CrOS

AMD ChromeOS has some issues with VP9 Profile 2 hw decoding. While
these are addressed, this CL adds a new
  disable_accelerated_vp9_profile2_decode
entry to gpu_workaround_list and uses it to prevent such decoding
from being tried.

This CL supersedes crrev.com/c/2518785.
