Significantly reduces BO allocation / destruction overhead for transfers,
e.g. measurable via x11perf -shm{ge,pu}t* with glamor.

This reverts commit 96e8b916a7.
In the case of VCE encoding with raw YUV file, CPU load directly
to VRAM is faster than combination of CPU writing to GTT and
then blit to VRAM with GPU.

When doing fast clear for single-sample color buffers for the first time,
a CMASK buffer has to be allocated and the CMASK state in all pipe_surfaces
referencing the color buffer must be updated. Updating all surfaces is kinda
silly, so let's move the values to r600_texture instead.
This is only for Evergreen and later. R600-R700 don't have fast clear.

v2: This doesn't change the behavior. It only moves the tiling check
to r600_init_resource and removes the usage parameter.

If we assume that all buffers allocated by the DDX are scanout, a new flag
that says "this is not scanout" has to be added to support the non-scanout
buffers and maintain backward compatibility.
This fixes bad rendering on Wayland.
The flag is defined as:
#define RADEON_TILING_R600_NO_SCANOUT RADEON_TILING_SWAP_16BIT
AFAIK, RADEON_TILING_SWAP_16BIT is not used on SI.

Textures that likely reside in VRAM, are mapped for reading and
don't require direct mapping should be staged into GTT, to avoid bad
performance. This fixes readback performance of VDPAU surfaces.

The function r600_choose_tiling is new and needs a review.
The only change in functionality is that it enables 2D tiling for compressed
textures on SI. It was probably accidentally turned off.
v2: don't make scanout buffers linear
