Overwriting UV map or vertex color data in Geometry nodes will move the layers to another CustomData channel, and as such, will make attribute lookup fail from the UVMap and Vertex Color nodes in EEVEE as the CustomDataType will also be modified (i.e. no longer `CD_MTFACE` or `CD_MCOL`). As discussed in T93179, the solution is to use `CD_PROP_AUTO_FROM_NAME` so that the render engine is able to find the attributes. This also makes EEVEE emulate Cycles behaviour in this regard. `attr_load_uv` and `attr_load_color` are also removed in favor of the generic attribute API in the various GLSL shaders. Although `CD_PROP_AUTO_FROM_NAME` is now used even for UV maps, the active UV map is still used in case the attribute name is empty, to preserve the old behavior.
