Subject: [PATCH] Fix NonStaticNestedClass: Make inner class static (#55501)

Summary:

The BaseVMFocusChangeListener inner class does not reference any members
of its outer class BaseViewManager. Making it static improves memory
efficiency by avoiding the implicit reference to the outer class instance.

Also removed the unused type parameter <V extends View> and changed the
method parameters from T to View since only View interface methods are used.
