KVM: VMX: Snapshot LBR capabilities during module initialization
Snapshot VMX's LBR capabilities once during module initialization instead of calling into perf every time a vCPU reconfigures its vPMU. This will allow massaging the LBR capabilities, e.g. if the CPU doesn't support callstacks, without having to remember to update multiple locations. Opportunistically tag vmx_get_perf_capabilities() with __init, as it's only called from vmx_set_cpu_caps().
