docs(specs,readme): narrow runtime Type-value support to type_name/type_is_unsigned [F0.8]

Browse Source 
The 7 type-only builtins doc claimed all of them accept a runtime Type
value, but only type_name and type_is_unsigned do. The other five
(size_of, align_of, field_count, type_eq, is_flags) are compile-time-only
— a runtime Type value (type_of(x)) yields 'unresolved type' since
runtime reflection is deferred. Reword both docs to the accurate scope.

Verified: type_name(type_of(x))=u32, type_is_unsigned(type_of(x))=true;
size_of(type_of(x)) / align_of(type_of(x)) -> error: unresolved type.
