Alexis Laferrière 59e0af702b Serialization: update for new diagnostics format ...

Make sure we flush the diagnostics consumers to prevent the new
diagnostic style to buffer the deserialization errors without printing
them. These errors may be printed right before an `abort()`, which would
bypass the actual printing of the errors.

Take advantage of the new style to make these diagnostics more readable
as well.

```
.../LibWithXRef.swiftmodule:1:1: remark: reference to type 'MyType'
broken by a context change; 'MyType' was expected to be in 'A', but now
a candidate is found only in 'A_related'
1 │ A.MyType
│ ├─ remark: reference to type 'MyType' broken by a context change;
'MyType' was expected to be in 'A', but now a candidate is found only in
'A_related'
│ ├─ note: the type was expected to be found in module 'A' at
‘.../A.swiftmodule'
│ ├─ note: or expected to be found in the underlying module 'A'
defined at ‘.../module.modulemap'
│ ├─ note: the type was actually found in module 'A_related' at
‘.../A_related.swiftmodule'
│ ├─ note: the module 'LibWithXRef' was built with a Swift language
version set to 5.10 while the current invocation uses 4.1.50; APINotes
may change how clang declarations are imported
│ ├─ note: the module 'LibWithXRef' has enabled library-evolution; the
following file may need to be deleted if the SDK was modified:
‘.../LibWithXRef.swiftmodule'
│ ├─ note: declarations in the underlying clang module 'A' may be
hidden by clang preprocessor macros
│ ├─ note: the distributed module 'LibWithXRef' refers to the local
module 'A'; this may be caused by header maps or search paths
│ ╰─ note: the type 'MyType' moved between related modules; clang
preprocessor macros may affect headers shared between these modules
.../LibWithXRef.swiftmodule:1:1: note: could not deserialize type for
'foo()'
1 │ A.MyType
  │ ╰─ note: could not deserialize type for 'foo()'
