[lldb] Expose structured errors in SBError (#120784)

Building on top of previous work that exposed expression diagnostics via
SBCommandReturnObject, this patch generalizes the support to expose any
SBError as machine-readable structured data. One use-case of this is to
allow IDEs to better visualize expression diagnostics.
