feat: keep well variables constant during poromechanics initizaliation

2

Useful for sequential, removes the need to create well rate tables with zero rate for t < 0

refactor: Single phase kernels - split into separate files

1

(didn't touch hybrid FVM and proppant)

needs to go after https://github.com/GEOS-DEV/GEOS/pull/3369

feat: Add functions to connect well perforation to surface elements

2

- move `calculateElementCenters` for subregions earlier into `FaceManager::computeGeometry`, so cell centers for surface elements are available when well perforation is processed - remove `registerWrapper` for `elementCenter` and `elementVolume` in `EmbeddedSurfaceSubRegion`,...

refactor: Preparatory for well to frac connection

3

This PR includes preparatory changes for supporting well to frac connections. - replace `CellElementSubRegion` with `ElementSubRegionBase` where possible - where not possible - use templates - introduce `targetRegion` for perforations,...

more or less ready for code review (a couple of missing pieces for flux derivatives), but needs more testing lots of duplication between multiphase and single phase solvers - to...

fix: try this density treatment for gravity

4

currently density in gravity term is `0.5(rho_i+rho_j)` where `i` and `j` are the cells here we are changing it to more commonly used treatment that checks phase presence leading to:...
