gallium: Add MULTISAMPLE_Z_RESOLVE cap
Resolving a multisampled depth texture into a single sampled texture is supported on >= SM4.1 hw. It is possible some previous hw support it. The ability was tested on radeonsi and nvc0. Apparently is is also supported for radeon >= r700. This patch adds the MULTISAMPLE_Z_RESOLVE cap and add it to the drivers. It is advertised for drivers for which it is sure the ability is supported. Reviewed-by: Marek Olšák <[email protected]> Signed-off-by: Axel Davy <[email protected]>
