mesa: Return LINEAR encoding for winsys FBO depth/stencil.

GetFramebufferAttachmentParameteriv should return GL_LINEAR for the
window system default framebuffer's GL_DEPTH or GL_STENCIL attachments
when there are zero depth or stencil bits.

The GL 4.5 spec's GetFramebufferAttachmentParameteriv section says:

"If the value of FRAMEBUFFER_ATTACHMENT_OBJECT_TYPE is not NONE,
 these queries apply to all other framebuffer types:

 [...]

 If attachment is not a color attachment, or no data storage or texture
 image has been specified for the attachment, then params will contain
 the value LINEAR."

Note that we already return LINEAR for the case where there is an actual
depth or stencil renderbuffer attached.  In the case modified by this
patch, FRAMEBUFFER_ATTACHMENT_OBJECT_TYPE returns FRAMEBUFFER_DEFAULT
rather than NONE.

cso: don't release sampler states that are bound

This fixes random radeonsi GPU hangs in Batman Arkham: Origins (Wine) and
probably many other games too.

cso_cache deletes sampler states when the cache size is too big and doesn't
check which sampler states are bound, causing use-after-free in drivers.
Because of that, radeonsi uploaded garbage sampler states and the hardware
went bananas. Other drivers may have experienced similar issues.

intel/blorp_blit: Add split_blorp_blit_debug switch

Enabling this debug switch causes surface shrinking to happen by
default, and lowers the surface size limit which causes blorp blits to
be split.

intel/blorp_blit: Enable splitting large blorp blits

Detect when the surface sizes are too large for a blorp blit. When it
is too large, the blorp blit will be split into a smaller operation
and attempted again.

For gen7, this fixes the cts test:

ES3-CTS.gtf.GL3Tests.framebuffer_blit.framebuffer_blit_functionality_multisampled_to_singlesampled_blit

It will also enable us to increase our renderable size from 8k x 8k to

intel/blorp_blit: Move RGB=>R conversion to follow blit splitting

In blorp_copy, when RGB surfaces are copied, we convert the
destination surface to a Red only surface, but 3 times as wide. This
introduces an implicit restriction of "mod 3" for the destination
width.

It is easier to handle the blorp split buffer offsetting with the
original RGB surface, and do the RGB=>R after this.

intel/blorp_blit: Split blorp blits if they are too large

We rename do_blorp_blit() to try_blorp_blit(), and add a return error
if the surface size for the blit is too large. Now, do_blorp_blit() is
rewritten to try to split the blit into smaller operations if
try_blorp_blit() fails.

Note: In this commit, try_blorp_blit() will always attempt to blit and
never return an error, which matches the previous behavior. We will
enable the size checking and splitting in a future commit.

The motivation for this splitting is that in some cases when we
flatten an image, it's dimensions grow, and this can then exceed the
programmable hardware limits. An example is w-tiled+MSAA blits.
