Encode::HanExtra takes too much memory to build

Autrijus,

  I tried to compile Encode::HanExtra 0.07 and found that it takes too 
much memory to build.  On my FreeBSD box it took over 200 MB RAM to 
build one.
  The reason is that Encode::HanExtra attempts to aggregate all 
mappings into one single giant *.c file.
Makefile.PL
> my $name = 'HanExtra';
> my %tables = (
>     HanExtra_t => [
>         qw(big5ext.ucm big5plus.ucm cccii.ucm euc-tw.ucm gb18030.ucm 
> unisys.ucm)
> ,
>         map "cns11643-$_.ucm", (1 .. 7, 'f'),
>     ],
> );

Encode::JP and other came accross the same problem during the 
development of Perl 5.8.0.  I made Encode::(CN|JP|KR|TW) so that it 
generates *.c for each mapping.  Though this increases the size of 
resulting *.so, it saves memory during the build significantly.
Here is the patch.  Same as what I did for Encode::(CN|JP|KR|TW).
