    golang/xenlight: generate structs from the IDL
    
    Add struct and keyed union generation to gengotypes.py. For keyed unions,
    use a method similar to gRPC's oneof to interpret C unions as Go types.
    Meaning, for a given struct with a union field, generate a struct for
    each sub-struct defined in the union. Then, define an interface of one
    method which is implemented by each of the defined sub-structs. For
    example:
    
      type domainBuildInfoTypeUnion interface {
              isdomainBuildInfoTypeUnion()
      }
    
      type DomainBuildInfoTypeUnionHvm struct {
          // HVM-specific fields...
      }
    
      func (x DomainBuildInfoTypeUnionHvm) isdomainBuildInfoTypeUnion() {}
    
      type DomainBuildInfoTypeUnionPv struct {
          // PV-specific fields...
      }
    
      func (x DomainBuildInfoTypeUnionPv) isdomainBuildInfoTypeUnion() {}
    
      type DomainBuildInfoTypeUnionPvh struct {
          // PVH-specific fields...
      }
    
      func (x DomainBuildInfoTypeUnionPvh) isdomainBuildInfoTypeUnion() {}
    
    Then, remove existing struct definitions in xenlight.go that conflict
    with the generated types, and modify existing marshaling functions to
    align with the new type definitions. Notably, drop "time" package since
    fields of type time.Duration are now of type uint64.
