Provide support for filter_path for all apis

[RolfDeVries]

Elastic.Clients.Elasticsearch version:
8.13.5

Elasticsearch version:
N/A

.NET runtime version:
.Net 8.0

Operating system version:
N/A

Description of the problem including expected versus actual behavior:
I'm upgrading from NEST 7.latest to the new Elastic.Clients.Elasticsearch version.
And I'm missing some features that are not yet supported

Steps to reproduce:

1. Create code to call a random api, any api will do:

   var response = await client.Cluster.StatsAsync(s => s
       .FilterPath(filterPath)
   );
   

Expected behavior
In the NEST 7 version, the FilterPath option was very easy to use
In the Elastic.Client.Elasticsearch 8 there is no support for this, please add it back for performance reasons

Provide ConnectionSettings (if relevant):

Provide DebugInformation (if relevant):

Hi @RolfDeVries,

thanks for reporting. It seems that the FilterPath setting currently is only available for the request classes (e.g. StatsRequest), but not the corresponding descriptors (StatsRequestDescriptor). I'll fix that in one of the next patch releases.

Thank you very much!
