Fixes studio mode preview on SDR monitor for HDR canvas rendering SDR
source into SDR swap chain. Needs to render SDR source into HDR render
target, and then tonemap into SDR swap chain for preview.
Due to the way the frontend works, the logic for inserting the row for
the group in the UI was dropped since the new item_add message will
insert one automatically since it forces a refresh of the scene items.
The reliance on that implicit row insertion when grouping items is a
bit of a code smell, although the alternative would be to add logic to
disable handling the signal for that instant, which is probably a
worse choice.
Rec. 2020 is really an SDR spec, but I think HDR10 made it okay to slap
PQ on it, call it an HDR spec. Rec. 2100 came along after and formally
allowed the use of PQ/HLG, so we should use 2100 instead.
This provides the framework for automatically compositing SDR and HDR
sources together. Source will need to leverage the new
video_get_color_space to opt into HDR support.
There are some cases where an item may attempt to be created for a
removed source.
Previously, items created from removed sources would lead to the item
itself being saved, but the underlying source not being saved. While
this does not break OBS immediately, it means that the source along
with all associated items will disappear on OBS reload.
This prevents the item from being created in the first place, reducing
the chances of user work being lost.
66c27c2cea (#4664) was mistakenly merged. It was also the incorrect
way to fix the deadlock. Because duplicate_item_data() already defers
the texture creation process, we can just add a param to
obs_scene_add_internal() which allows us to exclude the creation of the
item texture for this specific case. The texture will then automatically
be created later before it's used. There was no reason to be creating
the texture there, as it was unnecessary.

As logic in video render thread, gs lock (obs_enter_graphics) should be requested before full_lock(scene).
However in function obs_sceneitem_group_ungroup called from UI thread, the order for requesting locks are contrary.
In order to do linear-correct filtering cheaply when scale filtering is
disabled, we need to know whether or not texture coordinates will always
sample from texel centers. This can be computed at the scene item level
relatively easily, and passed along to sources when rendering. Scene
items will use obs_source_set_texcoords_centered to set hint status, and
sources will use obs_source_get_texcoords_centered to retrieve it.
Add OBS_SOURCE_SRGB to indicate sources that support SRGB rendering. We
can use this flag to know which sources do not know how to handle SRGB,
and disable accordingly inside obs_source_main_render().
We can also use this flag to clean up the filter interface and remove
the SRGB-specific functions. We also need to disable direct rendering if
the filter source wants to render SRGB, but the parent source does not
support it.
Scenes and groups are marked as having SRGB support, and those are
internal sources that we control.
Implements the Undo/Redo for scenes and sources, ranging from renaming,
deletion, addition. It also adds several elements to libobs that were
designed to facilitate undo/redo, and should not affect the rest of
libobs.
Removes prior attempt to expose libcaption headers which really shouldnt
have public. This instead moves the obs-internal include out of the
public obs-scene.h and into it's implementation.
As os_gettime_ns() gets large the current scaling methods, mostly by casting
to uint64_t, may lead to numerical overflows. Sweep the code and use
util_mul_div64() where applicable.

The id of the source was being pointer compared rather than string
compared, so naturally with the source versioning system where the
string is duplicated, the pointers no longer matched.
