Rollup merge of #122197 - lcnr:proof-tree-braces, r=BoxyUwU 
inspect formatter: add braces

This makes it easier to hide subtrees when looking through proof trees. Looking at the proof tree for `usize: Clone`:

nightly:
```
ROOT GOAL: Goal { predicate: Binder { value: TraitPredicate(<usize as std::clone::Clone>, polarity:Positive), bound_vars: [] }, param_env: ParamEnv { caller_bounds: [], reveal: UserFacing } }
    GOAL: Canonical { value: QueryInput { goal: Goal { predicate: Binder { value: TraitPredicate(<usize as std::clone::Clone>, polarity:Positive), bound_vars: [] }, param_env: ParamEnv { caller_bounds: [], reveal: UserFacing } }, anchor: Bind(DefId(0:5 ~ main[8e4b]::main)), predefined_opaques_in_body: PredefinedOpaques(PredefinedOpaquesData { opaque_types: [] }) }, max_universe: U0, variables: [] }
    REVISION 0
        INSTANTIATED: QueryInput { goal: Goal { predicate: Binder { value: TraitPredicate(<usize as std::clone::Clone>, polarity:Positive), bound_vars: [] }, param_env: ParamEnv { caller_bounds: [], reveal: UserFacing } }, anchor: Bind(DefId(0:5 ~ main[8e4b]::main)), predefined_opaques_in_body: PredefinedOpaques(PredefinedOpaquesData { opaque_types: [] }) }
        ROOT RESULT: Ok(Canonical { value: Response { certainty: Yes, var_values: CanonicalVarValues { var_values: [] }, external_constraints: ExternalConstraints(ExternalConstraintsData { region_constraints: QueryRegionConstraints { outlives: [], member_constraints: [] }, opaque_types: [] }) }, max_universe: U0, variables: [] })
            CANDIDATE Impl(DefId(2:30665 ~ core[a9f5]::clone::impls::{impl#5})): Ok(Canonical { value: Response { certainty: Yes, var_values: CanonicalVarValues { var_values: [] }, external_constraints: ExternalConstraints(ExternalConstraintsData { region_constraints: QueryRegionConstraints { outlives: [], member_constraints: [] }, opaque_types: [] }) }, max_universe: U0, variables: [] })
