mesa: raise max texture sizes to 16K
This allows 16K x 16K 2D textures, for example, but we don't want to allow that for 3D textures. The new gl_constants::MaxTextureMBytes field is used to prevent allocating too large of texture image. This allows a 16K x 32 x 32 3D texture, for example, but prevents 16K^3. Drivers can override this limit. The default is currently 1GB. Apps should use the proxy texture mechanism to determine the actual max texture size.
