x86,fs/resctrl: Rename struct rdt_mon_domain and rdt_hw_mon_domain

The upcoming telemetry event monitoring is not tied to the L3 resource and
will have a new domain structure.

Rename the L3 resource specific domain data structures to include "l3_"
in their names to avoid confusion between the different resource specific
domain structures:
rdt_mon_domain		-> rdt_l3_mon_domain
rdt_hw_mon_domain	-> rdt_hw_l3_mon_domain

No functional change.
