radeonsi: fix texture gather on stencil textures

At least on VI, texture gather doesn't work with a 24_8 data format, so
use 8_8_8_8 and a modified swizzle instead.

A bit of background: When creating a GL_STENCIL_INDEX8 texture, we select
the X24S8 pipe format because we don't support stencil-only render targets
properly. With mip-mapping this can lead to a setup where the tiling is
incompatible with stencil texturing, and a flushed stencil texture is
used. For the flushed stencil, a literal X24S8 is used because there were
issues with an 8bpp DB->CB copy.

Longer term, it would be good if we could get away from these workarounds,
i.e. properly support an S8 format for stencil-only rendering and flushed
stencil. Since stencil texturing is somewhat rare, it's not a high
priority.

mesa/main: Fix FRAMEBUFFER_ATTACHMENT_OBJECT_TYPE for NONE attachment type

When the attachment type is NONE (att->Type),
FRAMEBUFFER_ATTACHMENT_OBJECT_TYPE should be NONE always.

Note that technically, the current behaviour follows the spec. From
OpenGL 4.5 spec, Section 9.2.3 "Framebuffer Object Queries":

   "If the value of FRAMEBUFFER_ATTACHMENT_OBJECT_TYPE is NONE, then
    either no framebuffer is bound to target; or the default
    framebuffer is bound, attachment is DEPTH or STENCIL, and the
    number of depth or stencil bits, respectively, is zero."

Reading literally this paragraph, for the default framebuffer, NONE
should be only returned if attachment is DEPTH and STENCIL without
being allocated.

But it doesn't makes too much sense to return DEFAULT_FRAMEBUFFER if
the attachment type is NONE. For example, this can happens if the
attachment is FRONT_RIGHT run on monoscopic mode, as that attachment
is only available on stereo mode.

With the current behaviour, defensive querying of the object type
would not work properly. So you could query the object type checking
for NONE, get DEFAULT_FRAMEBUFFER, and then get and INVALID_OPERATION
when requesting other pnames (like RED_SIZE), as the real attachment
type is NONE.

This fixes:
GL45-CTS.direct_state_access.framebuffers_get_attachment_parameters

v2: don't change the behaviour for att->Type != GL_NONE, as caused
    some ES CTS regressions

i965: Make depth clear flushing more explicit

Current blorp logic issues unconditional "flush everything"

blits issue this unconditionally which shouldn't be needed if

In case of piglit:

in depth clears. By removing the brw_emit_mi_flush() I get gpu

At the moment we support 5+ different implementations each with varying

extra two configure toggles. Whist an actual implementation being
~200loc and our current compat wrapping ~250.

Let's not forget that different people use different code paths, thus
effectively makes it harder to test and debug since the default
implementation is automatically detected.

To minimise all these lovely experiences, import the "100% Public

to get building correctly, since many/most of those can be upstreamed
