until all platforms have landed the libs and the boolean
code actually lands in master.

if `WITH_GTESTS` is enabled.

CTest: Fix blender_test not working on windows.

MSVC does need the wholearchive flag but it was not set,
so no tests were actually linked into the binary.

Fix: Fix build error with MSVC in BLI_span_test

span.size() returns an uint, causing a signed/unsigned comparison
using 3u sidesteps the issue

MSVC: Fix build error with the 8.1 SDK

shobjidl_core.h only exists in the windows 10 SDK in the 8.1
SDK ShObjIdl.h will have the definitions we need, which still
exists in the 10 SDK and implicitly includes shobjidl_core.h.

so ShObjIdl.h will work on both SDK versions.

Cleanup: Fix build error with clang on windows.

Header and implementation signature for ED_object_add_duplicate
were not the same leading to a build error with clang on windows.

deps: Fix build issue with USD on windows.

When doing a release build the TBB debug libs are not
set which was causing an error during the configure
phase of USD, so always set them even if not used.

Build: upgrade OpenImageDenoise to 1.2.1

This requires ISPC for building OpenImageDenoise, so that is now added as
a dependency as well. Blender itself does not need ISPC for building so it
is not included as part of the precompiled libraries.

Fix T76767: Cycles performance regression with CLI renders

When picking a small tile size when doing a CLI render will
yield many status updates being printed to the console
causing a slowdown in the render process. 2.79 with the
same amount of tiles did not have this slowdown.

The reason for this turned out to be a debugging aid added
in rBd2757d149bf2 which disabled buffering for stdout which
on windows caused every single character being printed to the
console to try to obtain a mutex, and worse the thread being
put to sleep when this mutex was unavailable leading to poor
performance.

This patch changes the behaviour by only disabling the
buffering in debug builds.

CLI render of the default cube with 16x16 tiles at 1080p

2.83 : 37.57s
now : 17.03s

note: this only affected CLI renders, renders from the UI
do not report this kind of information and had no such
slowdown.
