Moving the class LayoutParams to a file outside CellLayout

I'm moving the LayoutParams to another file to start the decoupling
of the Reorder outside of the CellLayout.

Also, I change the name from LayoutParams to LauncherLayoutParams to prevent confusion with ViewGroup.LayoutParams making it explicit that this are different LayoutParams.

Bug: 188081026
Test: atest ReorderWidget
