Allow to change return value of onPreDraw in View.doOnPreDraw

[cypressious]

According to https://developer.android.com/reference/android/view/ViewTreeObserver.OnPreDrawListener#onPreDraw(), the return value of onPreDraw has the following use:

Return true to proceed with the current drawing pass, or false to cancel.

View.doOnPreDraw currently always returns true. Please allow to control the return value, e.g. by providing an overload with the parameter action: (view: View) -> Boolean

I agree on principle but I wonder if apps really need to ever return false. We do use this feature internally in the framework but it's tricky to use properly.
