Use visitor pattern for "maint print c-tdesc"

Target description can be modeled as a tree, the target description
is the root node, features are children nodes, registers and types are
grand-children nodes.  So command "maint print c-tdesc" in effect
traverse/visit each node, and print them in c.  This can be
implemented by visitor pattern, this is the first reason.  Secondly,
I want to this command prints c files in a different way for some
specific xml files, but still print c files the same way for the rest
of xml files.  Third, I even want to print xml files from target
descriptions, so that GDBserver can use it to reply GDB's query
qXfer:features:read:target.xml.
