KVM: x86: Dynamically calculate TDP level from max level and MAXPHYADDR
Calculate the desired TDP level on the fly using the max TDP level and MAXPHYADDR instead of doing the same when CPUID is updated. This avoids the hidden dependency on cpuid_maxphyaddr() in vmx_get_tdp_level() and also standardizes the "use 5-level paging iff MAXPHYADDR > 48" behavior across x86.
