[Telemetry] Expect to skip smoothness.maps on low-end devices

[Telemetry] Expect to skip smoothness.maps on low-end devices

Certain devices have ARM GPUs that report support of certain WebGL features but
fail to actually support them, causing smoothness.maps to fail. This CL adds
WebGLLowEndExpectations to skip tests like smoothness.maps on such devices.

I'd suggest naming these expectations per benchmark
("webgl_expectations.MapsExpectations") in case it turns out we need to
specialize them further.
