WebGL *textures/webgl_canvas* tests flaky on Windows 7 AMD

Project Member Reported by geoffl...@chromium.org, Aug 29

Issue description

Both the WebGL1 and WebGL2 versions of these tests are about 10% flaky on the Win7 FYI Release (AMD) bot.

Example flakes:
https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Win7%20FYI%20Release%20%28AMD%29/2402
https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Win7%20FYI%20Release%20%28AMD%29/2392
https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Win7%20FYI%20Release%20%28AMD%29/2389
https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Win7%20FYI%20Release%20%28AMD%29/2388

Earliest spotted flake is 13 days ago on August 16 but it is close to the 200 build limit so these tests may have been failing for longer:
https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Win7%20FYI%20Release%20%28AMD%29/2250

Failure is always an incorrect pixel color:
  AssertionError: shouldBe 0,255,0
  at (0, 0) expected: 0,255,0 was 72,72,72
  FAIL shouldBe 0,255,0
  at (0, 0) expected: 0,255,0 was 72,72,72

There are already some similar flaky suppressions, going to broaden them.  They were tracked in  issue 828984 .
