SF: Dev Options should force client composition for all frames

While there was some code which tried to force it, it turned out that if
there was a geometry refresh for a frame, the flag would be cleared
after being set. It would then be forced on subsequent frames assuming
there were no geometry updates then.

This was caught by the libsurfaceflinger_unittest I was trying to add,
which caught it when it was re-run after I moved more code to
CompositionEngine.

This patch moves where the flag is set to after where it was being
cleared, which meant adding a parameter, and adding a bit more unit test
coverage for the revised function.

Test: atest libsurfaceflinger_unittest # With added test there
Test: atest libcompositionengine_test # With added test there
