Subject: [PATCH] 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.
