va: Add VAConfigAttribEncMaxTileRows and VAConfigAttribEncMaxTileCols

Currently there is no way of exposing the driver tile_rows and tile_cols limitations for encoding with tiles. For codecs like AV1 there is a cap specifying the max number of tiles, but without differentiating cols/rows. Different hardware may have restrictions which may need to be taken into account. More specifically, D3D12 encode exposes the maximum rows/cols and adding VAConfigAttribEncMaxTileRows/Cols allows for mapping that information to the VAOn12 driver.
