selftests/resctrl: Extend CPU vendor detection
Currently, the resctrl_tests only has a function to detect AMD vendor.
Since when the Intel Sub-NUMA Clustering feature is enabled,
Intel CMT and MBM counters may not be accurate,
the resctrl_tests also need a function to detect Intel vendor.
And in the future, resctrl_tests will need a function to detect different
vendors, such as Arm.
Extend the function to detect Intel vendor as well. Also,
this function can be easily extended to detect other vendors.
