[SystemZ] Change default backend to ASCII (#174470)
The current (and default) backend on z/OS is EBCDIC.

This patch updates the default backend to be ASCII, which is beneficial
when porting new languages. With this change, ASCII is the default when
no special metadata nodes (such as `zos_le_char_mode`) are present.
