x86/resctrl: Kill off alloc_enabled
rdt_resources_all[] used to have extra entries for L2CODE/L2DATA.
These were hidden from resctrl by the alloc_enabled value.
Now that the L2/L2CODE/L2DATA resources have been merged together,
alloc_enabled doesn't mean anything, it always has the same value as
alloc_capable which indicates allocation is supported by this resource.
Remove alloc_enabled and its helpers.
