detect_apicv_cap should used to detect all the APICv capabilities. Besides,
"Virtualize x2APIC mode" doesn't depend on "APIC-register virtualization".
We shouldn't check "Virtualize x2APIC mode" support only when physical platform
supports "APIC-register virtualization"

Add two functions to combine constraint for APICv:
is_apicv_basic_feature_supported: check the physical platform whether support
"Use TPR shadow", "Virtualize APIC accesses" and "Virtualize x2APIC mode"
is_apicv_advanced_feature_supported: check the physical platform whether support
"APIC-register virtualization", "Virtual-interrupt delivery" and
"Process posted interrupts".
If the physical platform only support APICv basic feature, enable "Use TPR shadow"
and "Virtualize APIC accesses" for xAPIC mode; enable "Use TPR shadow" and
"Virtualize x2APIC mode" for x2APIC. Otherwise, if the physical platform support
APICv advanced feature, enable APICv feature for xAPIC mode and x2APIC mode.

This patch fixes the duplicated functions introduced by cpu caps
modularization.
In cpu caps modularization, function `is_vmx_disabled` was supposed
to be moved from `arch/x86/vmcs.c` to`arch/x86/cpu_caps.c`,
but the original one was not removed.
