Don't show OGR or GDAL entries for files in browser wherever another

provider is the preferred provider for a particular file

In particular, this allows us to hide the OGR entry for ept.json
files in the browser, so that instead we ONLY see an entry for the
EPT point cloud provider for these files. (Besides being clutter,
the OGR item for the ept.json file cannot be opened as a vector
layer so is just noise!)

(In the rare chance that a user DOES need to open a geojson file called
"ept.json" they can still do this easily via the Data Source Manager)
