This patch improves the StructuredData classes to provide a
GetDescription(lldb_private::Stream&) affordance.
This is very convenient compared to the Dump method because this try to
pretty print the structure instead of just serializing it into a JSON.
This patch also updates some parts of lldb (i.e. extended crash info) to
use this new affordance instead of StructuredData::Dump.
