soc/intel/apl: program VMX per Kconfig setting
While FSP programs the VmxEnable UPD per CONFIG_ENABLE_VMX, it doesn't
set the lock bit, which prevents Windows from enabling virtualization
on devices which support it. Call set_vmx_and_lock() to ensure the
lock bit is properly set.
TEST=build/boot Win11 on google/ampton,reef; verify virtualization
enabled.
