[Ada] Do not analyze expression functions for dispatch tables

tagged type for its dispatch table because they will be analyzed at the end
of the current scope.
gcc/ada/
* sem_attr.adb (Resolve_Attribute) <Attribute_Access>: Don't analyze
the body of an expression function in the case of a dispatch table.
