Since the previous commit ("exec/memory.h: make devend_memop
"target defines" agnostic") there is a single use of the
DEVICE_HOST_ENDIAN definition in ram_device_mem_ops: inline
it and remove its definition altogether.

In commit 98ed8ecfc9 ("exec: introduce target_words_bigendian()
helper") target_words_bigendian() was matching the definition it
was depending on (TARGET_WORDS_BIGENDIAN). Later in commit
ee3eb3a7ce ("Replace TARGET_WORDS_BIGENDIAN") the definition was
renamed as TARGET_BIG_ENDIAN but we didn't update the helper.
Do it now mechanically using:
$ sed -i -e s/target_words_bigendian/target_big_endian/g \
$(git grep -wl target_words_bigendian)

Currently the CPUClass:gdb_core_xml_file setting is a simple 'const
char *' which the CPU class must set to a fixed string. Allow the
CPU class to instead set a new method gdb_get_core_xml_file() which
returns this string.
This will allow Arm CPUs to use different XML files for AArch32 vs
AArch64 without having to have an extra AArch64-specific class type
purely to give somewhere to set cc->gdb_core_xml_file differently.

The documentation for the CPUClass::gdb_arch_name method claims that
the returned string should be freed with g_free(). This is not
correct: in commit a650683871 we changed this method to
instead return a simple constant string, but forgot to update
the documentation.
Make the documentation match the new semantics.

Some targets define cpu_list to a method listing their
CPUs on stdout. In order to make list_cpus() generic,
introduce the CPUClass::list_cpus() callback.
When no callback is registered, list_cpus() defaults
to the cpu_list definition.
