Chandler Carruth ae4be1be14 Use inline small storage for small SemIR ID sets in toolchain (#7796) ...

Apply SmallSize = 16 to frequent identifier and instruction/function
sets in ScopeStack, Class, FacetType, and SpecificCoalescer to avoid
dynamic heap allocations on small scopes. Also defer dest_field_names
set allocation in struct conversion and provide default KeyContext for
SetBase. This was found by inspection, but does seem to be a clear 1.5%
win on overall compile time.
