x86,fs/resctrl: Rename some L3 specific functions

With the arrival of monitor events tied to new domains associated with a
different resource it would be clearer if the L3 resource specific functions
are more accurately named.

Rename three groups of functions:

Functions that allocate/free architecture per-RMID MBM state information:
arch_domain_mbm_alloc()		-> l3_mon_domain_mbm_alloc()
mon_domain_free()		-> l3_mon_domain_free()

Functions that allocate/free filesystem per-RMID MBM state information:
domain_setup_mon_state()	-> domain_setup_l3_mon_state()
domain_destroy_mon_state()	-> domain_destroy_l3_mon_state()

Initialization/exit:
rdt_get_mon_l3_config()		-> rdt_get_l3_mon_config()
resctrl_mon_resource_init()	-> resctrl_l3_mon_resource_init()
resctrl_mon_resource_exit()	-> resctrl_l3_mon_resource_exit()

Ensure kernel-doc descriptions of these functions' return values are present
and correctly formatted.
