target-i386: Kill cpudef config section support
It's nice to have a flexible system to maintain CPU models as data, but
this is holding us from making improvements in the CPU code because it's
not using the common infra-structure, and because the machine-type data
is still inside C code.
Users who want to configure CPU features directly may simply use the
"-cpu" command-line option (and maybe an equivalent -device option in
the future) to set CPU features.
