PR Summary

Cmdlet was missing declaring OutputType which is ErrorRecord#PSExtendedError and Exception#PSExtendedError. Added OutputType attribute. Cmdlet adds the PSExtendedError typename and removes Exception and ErrorRecord typenames so that the formatting is used. The formatter then removes PSExtendedError and puts back the original typename so that $Error should be the same before calling Get-Error. While testing, had to make some changes to how InvocationInfo is retrieved so that ParseException which contains a nested ErrorRecord which as InvocationInfo is handled correctly. Combined Exception and ErrorRecord formatter into one.
