Physics object for porous media solid temperature conduction problem

[GiudGiud]

Motivation

gFHR inputs to be released on the VTB are a little long. There are also plenty of opportunities to get it wrong in their current form. An action / physics would do some good

Design

A PNSFVSolidHeatTransfer physics would do it

Impact

Easier time using Pronghorn Less mistakes made when modeling porous media flow
