op.h: Fixups for perlapi, Devel::PPPort

This commit clarifies in perlapi that these macros take a parameter that
is a CPP token, and that Devel::PPPOrt can't blindly gernerate test
cases for them.

 Set an entry in the BHK structure, and set the flags to indicate it is
 valid.  C<which> is a preprocessing token indicating which entry to set.
 The type of C<ptr> depends on the entry.

 Return a member of the XOP structure.  C<which> is a cpp token
 indicating which entry to return.  If the member is not set
 this will return a default value.  The return type depends
 on C<which>.  This macro evaluates its arguments more than
 once.  If you are using C<Perl_custom_op_xop> to retrieve a
 C<XOP *> from a C<OP *>, use the more efficient L</XopENTRYCUSTOM> instead.
