GetFramebufferAttachmentParameteriv should return GL_LINEAR for the

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

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

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.
