Add logging for GCS when workspaces are disabled, also add log for time taken to collect gcs data.

Be able to specify the location for GCS data in the native code when gcs workspaces are disabled. Visualization/GPB want to use it when loading up GPB in the kubernetes clusters. This is related to one of the experiments during the pineapple viewer hackathon.

Add env var GEOCOORD_DIR which can specify where the asset dir is located.

Why? Who will use this?

The Initialize function takes the data directory as an argument. Silently overriding that input with an undocumented environment variable is gross and surprising. Did you consider permitting the application to configure PlatformLib::IKnownLocationsAdmin::_GetGeoCoordinateDataDirectory?

I disagree with the whole concept of reading local data files. That capability should be removed entirely - it is not necessary and will only cause problems.

If somebody really wants to deliver GCS data with an application (I still don't understand why you can't use the cloud workspaces), they should use the existing api and add a local WorkspaceDb.

PLEASE DON'T DO THIS!
