[Impeller] MassiveScalingMatrixImageFilter test is crashing on CI #189286

The test already has a GTEST_SKIP exemption for Vulkan due to running out of memory with Swiftshader, but it is now crashing for OpenGLES[SDF] as well now that the test is actually being run in regular testing (as of #188889).

Note that it runs fine locally on a Macbook Pro with OpenGL (via Angle) most likely because there is more memory. Impeller will make sure it never allocates a texture larger than the backend says it supports (max texture size), but it looks like the platform cannot always satisfy a request that it claimed was for a "supported" size.

All 3 of these platforms are now exempted from the test via GTEST_SKIP, but we should investigate the underlying causes and reenable them for better testing.

Reproduce by removing the GTEST_SKIP from the test and creating a PR - the test should fail during pre-submit tests.
