lib: sbi_domain: Rename per-domain data to per-domain state

Browse Source 
The per-domain sbi_domain_data hold each domain
associated state like hart context in sbi_domain_context,
mpxy state in sbi_mpxy, and others like each domain backed
by the corresponding MPT (SMMPT).
DATA reads as a generic name, while every use stores state.
Rename functions and macros appropriately. There are no
functional changes.
