fs/resctrl: Update bit_usage to reflect io_alloc
The "shareable_bits" and "bit_usage" resctrl files associated with cache
resources give insight into how instances of a cache is used.
Update the annotated capacity bitmasks displayed by "bit_usage" to include the
cache portions allocated for I/O via the "io_alloc" feature. "shareable_bits"
is a global bitmask of shareable cache with I/O and can thus not present the
per-domain I/O allocations possible with the "io_alloc" feature. Revise the
"shareable_bits" documentation to direct users to "bit_usage" for accurate
cache usage information.
