tests: suspend/resume: Increase number of processed frames

The suspend/resume test starts a run of 300 frames and suspends the
system one second later. On some SoCs (namely H3 ES2.0) the VSP
bandwidth is high enough to complete processing of 300 frames in less
than a second. The test thus suspends and resumes the system with the
VSP idle instead of running, defeating the purpose of the test.

Fix this by increasing the number of frames to process to 1000. The
frame count is now passed as an argument to the
test_extended_wpf_packing function to ease future changes.

Changes since v1:

- Don't explicitly state at which frame suspend/resume is expected to
occur as that's device-dependent

- Compare the last three frames instead of just one
