Jon Ross-PerkinsandDana Jansens 3ae62f8130 Rewrite Dump calls to use std::string returns (#5195)
Thought this might be interesting for you to allow more continuous
stream use. Also eliminates the need for `DumpNoNewline`.

```
expr Dump(context, complete_type_id)
(std::string) $0 = "type(inst1553): <builtin i32>; {kind: IntType, arg0: signed, arg1: inst1508, type: type(TypeType)}"
complete_type_id.Dump()
(std::string) $1 = "type(inst1553)"
expr Dump(context, specific_id)
(std::string) $2 = "specific166: {generic: generic0, args: inst_block772}"
expr Dump(context, query_self_const_id)
(std::string) $3 = "concrete_constant(inst1510): {kind: ClassType, arg0: class0, arg1: specific166, type: type(TypeType)}"
expr Dump(context, MakeFacetTypeId(arg))
(std::string) $4 = "facet_type22: {impls interface: interface10}
  - interface10: {name: name26, parent_scope: name_scope0} `BitAnd`
complete: complete_facet_type22
  - interface10: {name: name26, parent_scope: name_scope0} `BitAnd` (to impl)"
```
