Oliver Anderson 39ee018b60 arch: Required MSR updates method on CpuProfile ...

We introduce a method on the CpuProfile enum that computes the required
MSR related updates in order to be compatible with the CPU profile.

The output of this function describes the feature MSRs that need to be
set and the snapshottable MSRs that are compatible with the chosen CPU
profile. The former provides the guest information about CPU features
(that are not obtainable from inspecting CPUID) while the latter is
used to ensure that MSRs that are incompatible with the CPU profile
are not set upon snapshot/restore.

These will be utilized in the vmm crate in a follow up commit.

We expect the hypervisor to take care of checking compatibility of the
feature MSRs when they are set. IA32_ARCH_CAPABILITIES is a known
exception however which we introduce our own checks for in a follow
up commit.
