x86: refactor psr: L3 CAT: implement get value flow.

There is an interface in user space to show feature value of
domains.

This patch implements get value flow in hypervisor.

It also changes domctl interface to make it more general.

With this patch, 'psr-cat-show' can work for L3 CAT but not for
L3 code/data which is implemented in CDP related patches.
