Hide the Pip menu on drag resize, expand and dismiss

- In drag resize, removes the call to #hideMenuWithoutResize
since that only triggered a menu state change but didn't actually
hide the menu view. The following call to hideMenu would also no-op
because of it. Instead, just call hideMenu with resize=false. This
will actually hide the menu view and then update the state.
- During expand pip, also use hideMenu(animate, resize) to
really hide the menu view - do not animate in this scenario
- During dismiss pip, also use hideMenu(animate, resize) to
really hide the menu view - do animate the menu fade here

Bug: 178391622
Test: Expand, dismiss, drag resize - make sure the menu hides
correctly
