hv: vCAT: initialize vCAT MSRs during vmcs init

Browse Source 
Initialize vCBM MSRs

Initialize vCLOSID MSR

Add some vCAT functions:
 Retrieve max_vcbm and max_pcbm
 Check if vCAT is configured or not for the VM
 Map vclosid to pclosid
 write_vclosid: vCLOSID MSR write handler
 write_vcbm: vCBM MSR write handler
