[Magnifier-74] Remove MAX_IN_VIEW sourcebound type

The CL removes the MAX_IN_VIEW type of source bounds, used to define
where the content of the magnifier can be copied from. MAX_IN_VIEW was
not used anywhere, and it is easily replaceable if developers need it:
setting the source bound to MAX_IN_SURFACE and use the View#getWidth()
and View#getHeight() methods to coerce the coordinates passed to the
show() methods.
