Add source projection information to map-sources

[theduckylittle]

Add a src-proj property to WFS sources to make configuring the projection information more explicit.

This will work with a WFS in its preferred projection.

[klassenjs]

I'm not sure on this one. I'm getting JS Console errors, but I might be doing it wrong. Is there docs/test case for this?

[theduckylittle]

@klassenjs see #542 for a test case. This latest version should be working properly with both EPSG:3857 layers and EPSG:4326 layers.

[brentfraser]

Display of WFS EPSG:4326 features works! But Identify and Select does not.

GeoMoose/OL sends a GetFeature request with a Filter containing
<PropertyName>geom</PropertyName>
which must be a default somewhere in the code. My two test servers report a geom name of msGeometry (e.g. see https://demo.mapserver.org/cgi-bin/wfs?SERVICE=WFS&VERSION=1.1.0&REQUEST=DescribeFeatureType )

I think we ran across this problem when implementing WFS-T and added:
<config name="geometry-name" value="wkb_geometry" />
to the map-source definition.

Or maybe the problem is the coordinate def / order (such a nightmare for WFS 1.0, 1.1, 2.0).

[klassenjs]

I think this needs a manual merge/rebase. I'm not seeing the vector parcels or pipelines layers on the map anymore (MapServer on the demo server is returning an error).

Note: tested with a local checkout of this branch and then a local git rebase main (which applied cleanly).

Here's my mapbook for testing this PR (AKA Issue #542 ), as well as Issue #772

Just making a comment here to say that the reason for search and identify not working may be related to the issue described in #346 which effectively is an issue inherited from MapServer WFS
