SF: Update RefreshRateSelectorTest to remove g_noSlowTests from some tests

Divided the test into multiple tests in the previous CL.
These tests should be able to execute on slow environment as well.

Test: atest libsurfaceflinger_unittest && atest SurfaceFlinger_unittest
&& atest libcompositionengine_test && atest CtsGraphicsTestCases
