[APX] i386: Use setzucc by default when APX-ZU enabled

When APX-ZU enabled, all legacy setcc can directly use zu sematic to
avoid potential partial-dependency.

gcc/ChangeLog:

* config/i386/i386.md (*setcc_qi): Force output setzucc for
reg operand[0].
(*setcc_qi_slp): Likewise.

gcc/testsuite/ChangeLog:

* gcc.target/i386/apx-zu-3.c: New test.
