Series disas: Have CPUClass::disas_set_info() callback set the endianness | expand

All CPUClass implementating disas_set_info() must set the
disassemble_info::endian value.

Ensure that by setting %endian to BFD_ENDIAN_UNKNOWN before
calling the CPUClass::disas_set_info() handler, then asserting
%endian is not BFD_ENDIAN_UNKNOWN after the call.

This allows removing the target_words_bigendian() call in disas/.
