Log error and assert in debug when multiple tilestores are created (#7556)

We often have an issue when multiple tilestores are created, that causes
slowness and problems with offline packs.
To help with this, added an error message in this case to log and in
debug it will also crash on an assert.

If you REALLY need to allow multiple tilestores, set this non persistent
setting to true before creating tilestores:
`"com.mapbox.common.tilestore.allow_multiple"`

Example error message:
Error, tile_store]: Creating duplicated TileStore in path
'/Users/olegfedorov/Documents/GitHub/mapbox-sdk/projects/common/test/tmp/TileStoreTest/CreateWithDuplicatePath/tile_store'.
You have now 2 TileStores created in these locations:
'/Users/olegfedorov/Documents/GitHub/mapbox-sdk/projects/common/test/tmp/TileStoreTest/CreateWithDuplicatePath,
/Users/olegfedorov/Documents/GitHub/mapbox-sdk/projects/common/test/tmp/TileStoreTest/CreateWithDuplicatePath/tile_store'.
This will cause performance issues, please use single TileStore for
everything.
