x86/resctrl: Rename the config option INTEL_RDT to RESCTRL
The resource control feature is supported by both Intel and AMD. So,
rename CONFIG_INTEL_RDT to the vendor-neutral CONFIG_RESCTRL.
Now CONFIG_RESCTRL will be used for both Intel and AMD to enable
Resource Control support. Update the texts in config and condition
accordingly.
[ bp: Simplify Kconfig text. ]
