Fix a handful of broken guest assert/printf messages, and annotate guest
ucall, printf, and assert helpers with __printf() so that such breakage is
detected by the compiler.

v2:
 - Annotate the relevant helpers. [Maxim]
 - Fix all other warnings (v1 fixed only the MWAIT error message)

v1: https://lore.kernel.org/all/20231107182159.404770-1-seanjc@google.com

Print out the test and vector as intended when a guest assert fails an
assertion regarding MONITOR/MWAIT faulting.  Unfortunately, the guest
printf support doesn't detect such issues at compile-time, so the bug
manifests as a confusing error message, e.g. in the most confusing case,
the test complains that it got vector "0" instead of expected vector "0".

Fixes: 0f52e4aaa614 ("KVM: selftests: Convert the MONITOR/MWAIT test to use printf guest asserts")

Convert %llx to %lx as appropriate in guest asserts.  The guest printf
implementation treats them the same as KVM selftests are 64-bit only, but
strictly adhering to the correct format will allow annotating the
underlying helpers with __printf() without introducing new warnings in the
build.

Swap the ordering of parameters to guest asserts related to {RD,WR}MSR
success/failure in the Hyper-V features test.  As is, the output will
be mangled and broken due to passing an integer as a string and vice
versa.

Opportunistically fix a benign %u vs. %lu issue as well.

Annotate guest printf helpers with __printf() so that the compiler will
warn about incorrect formatting at compile time (see git log for how easy
it is to screw up with the formatting).

Applied rather quickly to kvm-x86 selftests, as I want to get these a few days
