[gtk+] tests: Add gesture tests for early/late sequence claiming

commit 93f72985bf58c2d849699dceb146ab7909c54d45

    tests: Add gesture tests for early/late sequence claiming
    
    This tests both a sequence being claimed early to be then denied
    (and handled deeper in propagation chain), and a sequence being
    claimed late in the capture phase (and thus being cancelled deeper
    in the propagation chain)
