According to AMD's Speculative Return Stack Overflow whitepaper (link
below), the hypervisor should synthesize the value of IBPB_BRTYPE and
SBPB CPUID bits to the guest.
Support for this is already present in the kernel with commit
e47d86083c66 ("KVM: x86: Add SBPB support") and commit 6f0f23ef76be
("KVM: x86: Add IBPB_BRTYPE support").
Add support in QEMU to expose the bits to the guest OS.

is_host_cpu_intel() should return TRUE if the host cpu in Intel based, otherwise
it should return FALSE. Currently, it returns zero (FALSE) when the host CPU
is INTEL and non-zero otherwise. Fix the function so that it agrees more with
the semantics. Adjust the calling logic accordingly. RAPL needs Intel host cpus.
If the host CPU is not Intel baseed, we should report error.

kvm_filer_msr() is only used from i386 kvm module. Make it static so that its
easy for developers to understand that its not used anywhere else.
Same for QEMURDMSRHandler, QEMUWRMSRHandler and KVMMSRHandlers definitions.

Because the index value of the VMCS field encoding of FRED injected-event
data (one of the newly added VMCS fields for FRED transitions), 0x52, is
larger than any existing index value, raise the highest index value used
for any VMCS encoding to 0x52.
Because the index value of the VMCS field encoding of Secondary VM-exit
controls, 0x44, is larger than any existing index value, raise the highest
index value used for any VMCS encoding to 0x44.
