Embed Layers from a PostGIS DB project file

[gotjoshua]

Feature description

I love the embed layers feature, and it is also working great for qfield.
My dream is to be able to load a project that is itself very lightweight as it only points to layer groups from another projectfile. It would be epic, if both the source project and the pointer project could live in PostGIS.

Additional context

I can load single projects from PostGIS, but can't embed others.
I can load embeded layers from relative paths, but not from PostGIS.

I would love to be able to source embedded layers from a PostGIS DB.
