Device validation should not have to wait until command line

qemuxml2argvtest: add test for remove cpu features
CPU features that always were a no-op in qemu got removed there.
We no more specify them as that would trigger errors and fail to start
qemu. This test ensures that those features really are not rendered into
qemu command line.

Without the related fix this test will trigger and fail like:
 In 'tests/qemuxml2argvdata/cpu-no-removed-features.args':
 Offset 371
 Expect [ ]
 Actual [,-osxsave,-ospke ]

6864d8f740 qemuBuildMemoryBackendProps: Get pagesize early
https://bugzilla.redhat.com/show_bug.cgi?id=1693066

Up until memfd introduction (in 24b74d187c) we did not need to
know @pagesize because qemuGetDomainHupageMemPath() could deal
with it being zero (value of zero means use the default hugetlbfs
mount). But since for memfd we are not passing a path to
hugetlbfs mount rather the page size value we need to know its
value upfront.

97b729effe qemuxml2argvtest: Drop dependency between testInfoArgName and virQEMUCapsFlags enums
Introduced in fdf6c89ee7, this dependency looks weird. It was
needed because of the way that while() loop was written - it
fetches next argument in every iteration. Therefore, our only
option was for ARG_END to have the same value as QEMU_CAPS_LAST.
This also meant that QEMU_CAPS_* could have been only at the end
of the __VA_ARGS__.

This commit reworks the while() loop and removes the dependency.

087a74e160 qemu_capabilities; Drop virQEMUCapsSetVAList
There is one specific caller (testInfoSetArgs() in
qemuxml2argvtest.c) which expect the va_list argument to change
after returning from the virQEMUCapsSetVAList() function.
However, since we are passing plain va_list this is not
guaranteed. The man page of stdarg(3) says:

  If ap is passed to a function that uses va_arg(ap,type), then
  the value of ap is undefined after the return of that function.

(ap is a variable of type va_list)

I've seen this in action in fact: on i686 the qemuxml2argvtest
fails on the second test case because testInfoSetArgs() sees
ARG_QEMU_CAPS and calls virQEMUCapsSetVAList to process the
capabilities (in this case there's just one
QEMU_CAPS_SECCOMP_BLACKLIST). But since the changes are not
reflected in the caller, in the next iteration testInfoSetArgs()
sees the QEMU capability and not ARG_END.
