qemu/target-info: Factor target_arch() out

To keep "qemu/target-info.h" self-contained to native
types, declare target_arch() -- which returns a QAPI
type -- in "qemu/target-info-qapi.h".

No logical change.

Keeping native types in "qemu/target-info.h" is necessary
to keep building tests such tests/tcg/plugins/mem.c, as
per the comment added in commit ecbcc9ead2f ("tests/tcg:
add a system test to check memory instrumentation"):

/*
 * plugins should not include anything from QEMU aside from the
 * API header. However as this is a test plugin to exercise the
 * internals of QEMU and we want to avoid needless code duplication we
 * do so here. bswap.h is pretty self-contained although it needs a
 * few things provided by compiler.h.
