Fix T77774: New undo code broken by 'make local' behavior.

This is actually a nice issue due to too much optimization...
* Making an ID local just reuse the linked one whenever possible, instead of
actually making a copy of it.
* Therefore, the collection containing that ID is seen as unchanged, since
the pointer itself remained the same.
* But on undo step, there is no way to reuse that local object, which then
gets deleted, and linked one gets re-created - at a different address.
* Collection, however, since unchanged, is not updated at all and thus keeps
reference to the to-be-deleted local object, instead of the linked one.
* Issue gets even worse with viewlayers, this leads to the crash.

To address this, this patch adds a 'virtual' update flags that does nothing
in update case, but will ensure that the affected IDs using the one made local
are properly detected as changed across the relevant undo step.

Note that the recalc flags were chosen mostly for a logical reason, and also
because they are already properly dealt with and cleared by undo code,
so this looks like the optimal solution.

VR: Properly support outputting sRGB swapchain buffers

Latest SteamVR OpenXR updates brought OpenGL support, but only with sRGB
buffers. I think for DirectX it's the same now.
It's not a big issue for us to use sRGB buffers, so that's what I will
do for now. That way we shouldn't need hardcoded exceptions for specific
runtimes that don't transform linear buffers correctly.

Fix T78047: Fix failing denoiser tests on windows

When we switched to MSVC2019 and C++17 we seemingly
managed to trigger a code-gen bug with MSVC in the
AVX code-path.

This change works around the issue by (hopefully
temporary) disabling the optimizer for the fast_exp2f4
function, given it is only used in a single pass
of the denoiser and nowhere else, this is luckily
not as bad as it could have been.

Once the compiler is fixed or a different fix is
available we'll have to revisit this.
