`az pipelines runs list` does not support passing multiple values for `result`

[IanKemp]

The list builds endpoint supports passing multiple values for resultFilter, separated by commas. For example, the following will retrieve builds with any of the 3 provided results:

GET https://dev.azure.com/{org}/{project}/_apis/build/builds?resultFilter=failed,partiallySucceeded,succeeded

az pipelines runs list appears to allow only a single value for result:

> az pipelines runs list --result failed partiallySucceeded succeeded
unrecognized arguments: partiallySucceeded succeeded

> az pipelines runs list --result failed,partiallySucceeded,succeeded
az pipelines runs list: 'failed,partiallySucceeded,succeeded' is not a valid value for '--result'. Allowed values: canceled, failed, none, partiallySucceeded, succeeded.

Please can support for multiple values be added.
