A boolean comparison that involves at least one vector type will
result in a boolean vector (not a boolean scalar) for Direct3D and
Metal, whereas OpenGL returns a scalar boolean.
To avoid unnecessary code complexity, use the "distance" function
instead, which treats the color values as vectors and returns a
non-zero value if they are any different, achieving the same result.
This fixes a bug where the NVIDIA NVAFX filters are migrated but not
kept in their original order, with respect to other filters.

If speex and rnnoise are disabled but nvafx is enabled, the noise
reduction filter still needs to be built. This fixes the issue.

This commit does the following:
1. Factor out NVIDIA Audio Effects from Noise Suppression filter.
2. Move NVIDIA Audio Effects to a new filter in a new nv-filters
project.
3. Migrate Noise Suppression filter settings to the new filter when
NVIDIA Audio effects were used.
4. Migrate NVIDIA AI Greenscreen to the new nv-filters project for
easier maintainance of all NVIDIA Maxine effects.
Context:
Currently, the three NVIDIA Audio Effects (noise suppression, room
echo removal, noise suppression + room echo removal combined) are part
of the noise suppression filter.
Historically, it's because a lot of code was shared between speex,
rnnoise & NVIDIA noise suppression.
But the NVIDIA code has become bulkier & cumbersome due to:
- addition of other effects;
- addition of a deferred loading thread.
The factorisation makes the code very difficult to maintain for
(un)readability reasons.
This will make it easier to add other audio effects, should we wish to.
Developers life will be easier too when debugging.
The code has been reorganized and comments added.
I also added a mutex in the process_fx function to avoid a crash when
swapping effects.

Flag was added in CMake 2.0 update and is incompatible with incremental
linking enabled by default for Debug configuration (MSVC default).
The original error that necessitates adding LTCG is not present with
current obs-deps anymore, so remove it instead and disable the
hard-coded default library directive in Debug configuration.
This pattern uses fewer instructions and also avoids using max, which
does not work on infinity.
Also remove unreferenced techniques from scale filters.
This fixes a bug when swapping NVIDIA effects.
The update signal triggers a destruction of the previous effect, but the
effect would still run, potentially causing a crash.
The mutex added in the NVIDIA processing function prevents that.

We need to check for new versions of the NVIDIA Effects redistributables
because mismatched versions of the AUDIO and VIDEO sdk can have
different CUDA versions of the deps, which has caused crashes in obs.
It'd be way better that NVIDIA either ships a single installer with both
audio and video effects or that they auto-install with the drivers.
But meanwhile, we provide a warning to users which requires us to keep
in sync with what's released.

Creation of Info.plist files through Xcode is more canonical and
future-proof, as it will automatically pick up changes/updates
introduced by Apple. Non-standard keys can still be added via a
template file, which will then be extended by Xcode with the default
keys.
