A new qemuDomainDefValidateNuma() function was created to host
all the QEMU caps validation being done inside qemuBuildNumaArgStr().
This new function is called by qemuDomainValidateCpuCount()
to allow NUMA validation in domain define time.
Tests were changed to account for the QEMU capabilities
that need to be present at domain define time.

Next patch will validate QEMU_CAPS_NUMA_DIST in a new qemu_domain.c
function. The code to verify if a NUMA node distance is being
set will still be needed in qemuBuildNumaArgStr() though.
To avoid code repetition, let's put this logic in a helper to be
used in qemuBuildNumaArgStr() and in the new function.

As part of a goal to eliminate the need to use virCapsPtr for anything
other than the virConnectGetCapabilies() API impl, cache the host arch
against the QEMU driver struct and use that field directly.
In the tests we move virArchFromHost() globally in testutils.c so that
every test runs with a fixed default architecture reported.

In this case, the virNetDevBandwidthPtr that is returned is not to a
region within the virDomainNetDef arg, but points elsewhere (the
NetDef has the pointer, not the entire object), so technically it's
not necessary to make the return value a const, but it's a bit
disingenuous to *not* do it.

In few places we have the following code pattern:
int ret;
... /* @ret is not accessed here */
ret = f(...);
return ret;
This pattern can be written less verbose:
...
return f(...);
This patch was generated with following coccinelle spatch:
@@
type T;
constant C;
expression f;
identifier ret;
@@
-T ret = C;
... when != ret
-ret = f;
-return ret;
+return f;
Afterwards I needed to fix a few places, e.g. comment in
virDomainNetIPParseXML() was removed too because coccinelle
thinks it refers to @ret while in fact it doesn't. Also in few
places it replaced @ret declaration with a few spaces instead of
removing the line. But nothing terribly wrong.

This device is a very simple framebuffer device supported by qemu that
is mostly intended to use as a boot framebuffer in conjunction with a
vgpu. However, there is also a standalone ramfb device that can be used
as a primary display device and is useful for e.g. aarch64 guests where
different memory mappings between the host and guest can prevent use of
other devices with framebuffers such as virtio-vga.
