test: Replace _TEST_CASE_ with _TEST_SUITE_ in /content/renderer/media/webrtc/rtc_video_encoder_unittest.cc.

Googletest is (at last) converging with industry-standard terminology
[1]. We previously called test suites "test cases", which was rather
confusing for folks coming from any other testing framework.

Chrome now has a googltest version that supports _TEST_SUITE_ macros
instead of _TEST_CASE_, so this CL cleans up some of the outdated usage.
