Get a tile coordinate given a map coordinate and zoom level.
@param {import("../coordinate.js").Coordinate} coordinate Coordinate.
@param {number} z Integer zoom level, e.g. the result of a `getZForResolution()` method call
@param {import("../tilecoord.js").TileCoord} [opt_tileCoord] Destination import("../tilecoord.js").TileCoord object.
@return {import("../tilecoord.js").TileCoord} Tile coordinate.
