Parameterize some tests using kCompositorTouchAction

This CL parameterize some tests using this flag. It does 2 things:
1. Move the kCompositorTouchAction flag from content/ to ui/events/blink.
This is because InputHandlerProxy will need to have access to this flag,
and that content/ depends on ui/events/blink.
2. Parameterize necessary tests based on this flag. Tests include:
InputRouterImplTest, TouchActionFilterTest, InputHandlerProxyTest,
TouchActionBrowserTest.

In order to pameterize the InputRouterImplTest, we have to extract a
InputRouterImplTestBase. The reason is that InputRouterImplTest has a
subclass "TouchpadPinchInputRouterImplTest", which is already a
parameterized test depending on another flag.
