lvconvert: use command defs for raid/mirror types

Browse Source 
All lvconvert functionality has been moved out of the
previous monolithic lvconvert code, except conversions
related to raid/mirror/striped/linear.  This switches
that remaining code to be based on command defs, and
standard process_each_lv arg processing.  This final
switch results in quite a bit of dead code that is
also removed.
