Cleanup/MSVC: Enable C++ conformance mode on compiler versions that support it.

MSVC has a conformance mode (/permissive-) where the C++ standard is more strictly
enforced. This mode is available on MSVC 15.5+ [1]

This patch enables this mode on compilers that support it and cleans up the few violations it threw up in the process.

- Mantaflow was using M_PI without requesting them using the _USE_MATH_DEFINES define to opt in to non default behaviour.
- Collada did not include the right header for std::cerr, this seemingly was fixed for other platforms already but put inside a platform guard.
- Ghost had some scoping issues regarding uninitialized variables and goto behaviour

Second landing of this patch, earlier commit was reverted due to some compiler configurations having slipped though testing

Freestyle: Add option for rendering Freestyle to a separate pass

This allows for more flexibility in Compositing compared to the
hardcoded alpha-over that is currently used.

DRW: Fix color management in material/rendered mode

We only do exposure/gamma if not using scene lighting

Add initial, very basic save/open & library linking blendfile tests.

Do not do much for now, but would have been enough to catch the crash
introduced the other day in linking code...

Py API: Add `orphans_purge` helper to `bpy.data`.

Much more convinient than trying to use outliner operator...

Fix for fix (c) assert from own recent commit.

This master_collection thing is really, really annoyingly spreading all
over the place...

Cleanup: add clarifying comment to ViewLayer->layer_collections

Fix (unreported) private/embedded IDs being added to `bpy.data.user_map()` dict.

We do not want those here.

Fix (unreported) fully broken `bpy.data.user_map()` helper.

The introduction of python instancing for ID data in 2.80 completely
broke the 'smart & efficient' hack of using a same py object as key for
initial quick check, since rebuilding the RNAPointer in the
BPy_StructRNA would actually affect the py instance of the first ID used
to generate that py object...

TL;DR: No need for this complex and unclear optimization anymore, since
we do not actually rebuild a whole py object anymore every time we call
`pyrna_id_CreatePyObject()` from a same ID pointer.

libquery: Add 'owner id' to callback data.

In some cases it's important to always have a proper ID as reference,
e.g. whene generating data supposed to represent main data-base...

Cleanup old special cases from some libquery callbacks.

We now have proper flagging for horrible loopback pointers...

Refactor libquery ID looper callback to take a single parameter.

Using a struct here allows to change given parameters to the callbacks
without having to edit all callbacks functions, which is always noisy
and time consuming.

Fix OptiX denoising when multiple CUDA streams are active

Cleanup: Remove some unnecessary OptiX device code

Cloth: Optimization in self collision

15% to 20% improvement in cloth simulation performance with
self-collision.

The idea is to reduce the number of collisions computed by avoiding
overlapping tris with the same combination (eg. (1,0) and (0,1)).
