[processing] Brand new generate elevation profile image algorithm

PR Description:

Description

This PR adds a brand new generate elevation profile image algorithm to the processing toolbox:

This can come in super handy as part of models that need to output elevation profiles for multiple curves.

I've tried to find a balance in picking the parameters exposed here. There would be plenty more to do, but unsure how much further we should go :)

By default, the algorithm will set the elevation profile plot's distance (X axis) and elevation (Y axis)'s minimum and maximum to match the curve length and Z range of the rendered layers. Users can manually overwrite these set via advanced parameters:
