views: remove ViewTest.RerouteMouseWheelTest

This test:
a) Predates Aura
b) Has been disabled since 2011
c) Doesn't compile any more because it was #if 0'd out in 2016

Even if it did still compile, it wouldn't work - it requires multiple
real native widgets and control over their activation, which won't work
in a unit test.
