Geometry Nodes: implicit position input in Set Position node

This change makes the Set Position node do nothing by default.
Before, the geometry would always disappear, because it all points
would be moved to (0, 0, 0).

UI: Change "Favorites" to "Bookmarks"

Change of File Browser "Favorites" section header in source list
(T panel) to "Bookmarks" to maintain consistency with all the other
bookmark-related text and operations.

See D10262 for more information and alternatives considered.

GPencil: Fix error in previous commit

By error I commited the previous version.

GPencil: Change Rotation tooltip

The tooltip was not clear about in what shading modes works.

Cleanup: spelling (correct c5c8c68eec93e57ed46be4371d8831e2f0fe3fe2)

"iff" was intended as "if and only if". while exact use of abbreviations
isn't clear cut, I assumed this was a typo & it's not used anywhere
else in source/, expand to "only if" (suggested by Sybren).

Build: change make update to not print errors regarding submodule branches

Instead of trying to checkout non-existent branches and getting confusing fatal
error prints, check if the branch exists first.

Geometry Nodes: support Noise Texture node

This makes the Noise Texture node available in geometry nodes.
It should behave the same as in shader node, with the exception
that it does not have an implicit position input yet. That will
be added separately.

Geometry Nodes: support Set Position node on instances

Previously, the node would always realize instances implicitly.
Now it can change the position of entire instances.
The Realize Instances node can be used before if the old
behavior is required.

make_update: Fix case where a sub-module would not have required branch.

Issue revealed by rB546314fc9669 change, also error itself exited before
that commit.

Now we do accept git command to fail when trying to checkout the
specified branch from sub-modules, and only actually error in case the
fall-back branch (aka master) cannot be properly checked out.

Thanks fot Ray molenkamp (@LazyDodo) for report and initial patch
(D12560).

Geometry Nodes: new Realize Instances node

This node has a simple geometry input and output.
If the input geometry contains instances, they will be realized
into actual geometry. When there are many instances, this can
be very slow and memory intensive. Generally, instances should
only be made real when necessary, e.g. when every instance
should be deformed independently.

UUID: add nil value for UUIDs

Add `BLI_uuid_nil()` that returns the nil UUID (used to indicate "not
set") and `BLI_uuid_is_nil(uuid)` to do an equality test with the nil
value.

UUID: include 'seconds' field of current time in RNG seed

XOR the 'seconds' and 'nanoseconds' fields of the current time to seed the
RNG used for generating random UUIDs. This ensures a better seed just in
case the clock as no sub-second resolution.

Cleanup: UUID, prevent "missing braces" warning on macOS

Add braces around initialization of sub-objects, as per the warning
suggestion on macOS.

No functional changes.

UUID: fix seeding the RNG clock on macOS

On Apple machines, call `clock_gettime()` instead of `timespec_get()`.

macOS only introduced `timespec_get()` in version 10.15 (introduced
approx two years ago, so in 2019), even though the function is from C11.

Fix T91511: GPencil weight_get and Vertex Groups not working at expected

Cleanup: spelling

Fix: Incorrect default values for the curve trim node

The default end factor should be 1. The proper value for the default end
length is somewhat arbitrary, but it shouldn't be zero.

Fix: Spline length calculation fails with no evaluated points

The case that checked whether there were evaluated edges was incorrect,
since two points are needed for an edge. Then also avoid running the
accumulation for an empty span.
