Improve tracking Tile installation

[luizgrp]

Since getActiveTilesAsync became available, our guidance should be updated to use it, instead of using the information provided by onTileAddEvent and onTileRemoveEvent.

---

Suggestion:

1. Remove markTileAsInstalled and markTileAsRemoved functions;
2. Add function to update the tracking of installed tiles:

    public suspend fun updateInstalledTiles() {
        val activeTiles = TileService.getActiveTilesAsync(context, executor).await()

        surfacesInfoDataStore.updateData { info ->
            info.copy {
                tiles.clear()
                for (activeTileIdentifier in activeTiles) {
                    tiles.add(tileInfo {
                        timestamp = System.currentTimeMillis().toProtoTimestamp()
                        name = activeTileIdentifier.componentName.className
                    })
                }
            }
        }
    }

3. Update guidance in https://google.github.io/horologist/datalayer-helpers-guide/ to call updateInstalledTiles in onTileAddEvent and onTileRemoveEvent.
