KVM: x86: Add mode-aware versions of kvm_<reg>_{read,write}() helpers

Make kvm_<reg>_{read,write}() mode-aware (where the value is truncated to
32 bits if the vCPU isn't in 64-bit mode), and convert all the intentional
"raw" accesses to kvm_<reg>_{read,write}_raw() versions.  To avoid
confusion and bikeshedding over whether or not explicit 32-bit accesses
should use the "raw" or mode-aware variants, add and use "e" versions, e.g.
for things like RDMSR, WRMSR, and CPUID, where the instruction uses only
bits 31:0, regardless of mode.

No functional change intended (all use of "e" versions is for cases where
the value is already truncated due to bouncing through a u32).
