Carlos López b8f7e9ea80 lib: sbi_locks: annotate spinlock APIs for TSA ...

Add Thread Safety Analysis (TSA) annotations for spinlock APIs, allowing
the compiler to reason about lock acquisition and release.

Annotations have a different meaning if used in header declarations vs C
file implementations. In header declarations, they specify the semantics
of the given function, meaning that we must specify that the spinlock
functions acquire and release a lock ("capability" in clang terms).
In function implementations, attributes affect the function body and
callers in the same translation unit; since the spinlock functions
contain inline assembly, they must be excluded from analysis.
