Split the depsgraph allocation into a separate function
`BKE_scene_ensure_depsgraph()`. Parameters are only passed to those
functions that actually need them. This removes the the "if that boolean
is `false` this pointer is allowed to be `NULL`" logic and more cleanly
decouples code.
No functional changes.
In last set of refactoring patches, code implementing this feature
has been accidentally removed.

This is the first step for having sequences covered with session UUID
with the goal to remove code which uses original sequence pointer to
match sequences.
Currently this UUID is maintained on file load, allocation and leaf
duplication function.There are more cases to cover and ensure UUID
is re-generated or re-used when needed. It will be done as follow-up
development.
Operator logic is limited to iterating over selection and executing
same code as python API does.
Functional changes:
- No attempt to preserve effects is made. Dependant effects are deleted.
- No attempt to change meta strip boundaries.

Add recursion check before assigning strip as a mask for modifier.
Same check is used for recursion check when reassigning effect input, so it

Custom driver functions need access to the dependency graph that is
triggering the evaluation of the driver. This patch passes the
dependency graph pointer through all the animation-related calls.
Instead of passing the evaluation time to functions, the code now passes
an `AnimationEvalContext` pointer:
```
typedef struct AnimationEvalContext {
struct Depsgraph *const depsgraph;
const float eval_time;
} AnimationEvalContext;
```
These structs are read-only, meaning that the code cannot change the
evaluation time. Note that the `depsgraph` pointer itself is const, but
it points to a non-const depsgraph.
FCurves and Drivers can be evaluated at a different time than the
current scene time, for example when evaluating NLA strips. This means
that, even though the current time is stored in the dependency graph, we
need an explicit evaluation time.
There are two functions that allow creation of `AnimationEvalContext`
objects:
- `BKE_animsys_eval_context_construct(Depsgraph *depsgraph, float
eval_time)`, which creates a new context object from scratch, and
- `BKE_animsys_eval_context_construct_at(AnimationEvalContext
*anim_eval_context, float eval_time)`, which can be used to create a
`AnimationEvalContext` with the same depsgraph, but at a different
time. This makes it possible to later add fields without changing any
of the code that just want to change the eval time.
This also provides a fix for T75553, although it does require a change
to the custom driver function. The driver should call
`custom_function(depsgraph)`, and the function should use that depsgraph
instead of information from `bpy.context`.

It was already possible to create Sound and Image strips that reference
non-existing files. Now it's also possible to create Movie strips
referencing missing files via the Python API call
`Sequences.new_movie()`. In this case, the duration of the strip will be
set to 1 frame.
Note that this commit does not change anything in the user interface.
The Python API of the `MovieStrip` class is extended with a function
`reload_if_needed()`. This function only performs disk I/O if the movie
strip cannot produce frames, that is either when its filepath points to
a non-existing file, or when the video sequence editor has not been
shown yet (for example because it is in an inactive workspace).
This allows for the following:
```
import bpy
scene = bpy.context.scene
vse = scene.sequence_editor_create()
filepath = bpy.path.abspath('//demo.mkv')
strip = vse.sequences.new_movie("movie", filepath,
channel=2,
frame_start=47,
file_must_exist=False)
strip.frame_final_end = 327
```
This will create a new movie strip, even when `demo.mkv` does not exist.
Once `demo.mkv` has appeared at the expected location, either
`strip.reload_if_needed()` or `strip.filepath = strip.filepath` will
load it.

Make sure that proxy and original images are scaled to same size before
applying offset or crop.
During testing, I discovered, that raw cache will lose information whether
this image was proxy or not. Because of this, proxy images will not create
this cache type. It would be fairly easy to implement this functionality for
cache, but I have decided to not do it now, because I did not want to pass yet
another mostly hard-coded bool flag to cache system. Since image is proxy, it
should be fast to read anyway.
In case of using offset property, code was modified to make sure we scale
image only once. I also tried to make code more readable and streamlined and
cleaned up surrounding functions a bit.
