Fix/ins coupled stability solver

This MR fixes the coupled stability solver.

See merge request !508

New points was not being updated in the correct place. Fixed by moving position of updating ppe map

The equispacedoutput was not working which also affected the isocontour extraction. There was an initialisation issue on one array which seem to be the problem so this fix addresses that. There will be a subsequent branch introducing a regression test.

Surface mesh distance filter for FieldConvert

Add a surface mesh distance process module for FieldConvert, that can used to, for example, calculate y+ values with the assistance of the wall shear stress module.

MeshConvert module to extract prism-tet interface

This MR introduces a new `MeshConvert` module to extract the prismatic boundary layer, identify the interface between prismatic and tetrahedral elements and add the necessary composite to enable simulations to be performed on a sub-region of the domain.

Feature/backtrace

this appends a nice backtraceto NekError to make it more obvious where the exception was thrown. Buildbot was successful. It looks like this:
