[PATCH 1/2] x86/vmx: Calculate model-specific LBRs once at start of day

There is no point repeating this calculation at runtime, especially as it is in the fallback path of the WRSMR/RDMSR handlers. Move the infrastructure higher in vmx.c to avoid forward declarations, renaming last_branch_msr_get() to get_model_specific_lbr() to highlight that these are
