lib: sbi_domain: add TSA annotations

Browse Source 
Add Thread Safety Analysis (TSA) annotations for the domain handling
code. This includes indicating which fields are protected by a spinlock,
and annotating which functions acquire a spinlock, in order to prevent
nesting. Exclude sbi_domain_register() from analysis, as it initializes
a domain's spinlock.
