SF: Add test for FrameStats refresh rate 

Adds a Transaction_test to ensure that the refresh rate field of
FrameStats is properly initialized. This is also caught by CTS, but
adding the test here should avoid a long round-trip time.

Bug: 111854867
Test: Manual, test catches regression fixed by ag/4663082
