Geometry Nodes: Allow for one vertex in grid node

This commit allows setting the number of vertices in either direction
to 1, so that the primitive grid node will create a line instead of a
grid. To avoid confusion the soft limits of the input sockets are not
changed, so this is purely an increase in flexibility for when it is
helpful.

Fix: Circle mesh primitive outer edges do not render

weren't marked with the flags that makes them show in wireframe

Fix BLI_strncpy_wchar_from_utf8 result on Windows

This function was documented to return the length but returned an
error value for WIN32. While this doesn't cause any bugs at the moment,
it could cause problems in the future.

BLI_string_utf8: add buffer size arg to BLI_str_utf8_from_unicode

Besides helping to avoid buffer overflow errors this reduces complexity
of BLI_str_utf32_as_utf8 which needed a special loop for the last 6
characters to avoid writing past the buffer bounds.

Also add BLI_str_utf8_from_unicode_len which only returns the length.

BLF: remove checks for blend file relative paths

This was added in b24712a9ca6fa807660a02d6988269748daecdbf
but is no longer needed as of efc129bc827558e55cf4619b8e2ca502342338f3.

Further, this wasn't reliable as it could fail on linked library data
which has a different base directory.

Assert when blend file relative paths are passed to BLF
(matching imbuf file loading).

Cleanup: Remove redundant null check

Fix failing alembic test after IDProperty UI data refactor

The default float IDProperty min value rB8b9a3b94fc148d19 for when there
is no UI data was FLT_MIN instead of -FLT_MAX, which meant that animated
custom property values couldn't be less than zero unless they had their
UI data values edited previously.

That's a mistake I won't make again! Also change the int minimums from
-INT_MAX to INT_MIN to sanitize the whole situation.

UI: Reduce Node Contents Jiggling When Moved

This patch just clamps and rounds node contents and socket locations
so they don't appear to jiggle around when you move them. This issue
happens because node sizing and positioning are in floats while text
content must be pixel-aligned.

See D11684 for more details and comparisons.

UI: Fix summary overlay wrong range and overlap in Dopesheet

The overlay was drawn twice on top of each other making it hard to see,
hard to theme, and making it more prominent in the wrong areas (before
frame 0, not even start frame). The comment in the code was also wrong
since it said "frame one" but it was 0.

Checked with the Animation module team that it's better to use start/end
frame range instead of frame 0.

There is a TODO note to de-duplicate this section eventually so I left it there.
This fix is currently done for Grease Pencil and Mask modes, but it should
also be fixed for the regular Dopesheet mode (in line 244 if anyone wants to do it).

Refactor IDProperty UI data storage

The storage of IDProperty UI data (min, max, default value, etc) is
quite complicated. For every property, retrieving a single one of these
values involves three string lookups. First for the "_RNA_UI" group
property, then another for a group with the property's name, then for
the data value name. Not only is this inefficient, it's hard to reason
about, unintuitive, and not at all self-explanatory.

This commit replaces that system with a UI data struct directly in the
IDProperty. If it's not used, the only cost is of a NULL pointer. Beyond
storing the description, name, and RNA subtype, derived structs are used
to store type specific UI data like min and max.

Note that this means that addons using (abusing) the `_RNA_UI` custom
property will have to be changed. A few places in the addons repository
will be changed after this commit with D9919.

**Before**
Before, first the _RNA_UI subgroup is retrieved the _RNA_UI group,
then the subgroup for the original property, then specific UI data
is accessed like any other IDProperty.
```
prop = rna_idprop_ui_prop_get(idproperties_owner, "prop_name", create=True)
prop["min"] = 1.0
```

**After**
After, the `id_properties_ui` function for RNA structs returns a python
object specifically for managing an IDProperty's UI data.
```
ui_data = idproperties_owner.id_properties_ui("prop_name")
ui_data.update(min=1.0)
```
In addition to `update`, there are now other functions:
- `as_dict`: Returns a dictionary of the property's UI data.
- `clear`: Removes the property's UI data.
- `update_from`: Copy UI data between properties,
even if they have different owners.

Fix crash sampling render result before any pixel was rendered

Caused by recent lazy render result passes allocation change.

Fix shadowing in sequencer iterator

The __LINE__ was not properly expanded.

Fix "toggle shading" op not updating VR view

Reason was that the notifier did not set the NS_VIEW3D_SHADING
subtype, which the VR view listens for for a shading update.

In the case of "toggle xray", a notifier was absent altogether.

VSE: Transform overwrite mode

Add mode to overwrite strips on overlap instead of resolving overlap.

When overlap is created, 3 things can happen:
- On partial overlap, handles of overlapped strip are moved
- On complete overlap with smaller strip, overlapped strip is split
- On complete overlap with larger strip, overlapped strip is removed

This mode can be enabled in header.

Fix T90907: RNA pointers for material slots are not unique across IDs

Caused by {rB1a81d268a19f}.

This caused e.g. ALT-clicking the 'Link' button to not propagate to
other selected objects (same as the 'Copy To Selected' context menu
entry).

If these are not unique across IDs, checks in ui_selectcontext_begin()
or copy_to_selected_button() could fail.

Now offset by ID pointer.

thx @JacquesLucke for clarification on the POINTER_* macros (and why
not to use them)!

Fix XR action map index initialization

This reverts 151eed752b01. Originally thought it was necessary to
initialize selected/active indices to -1 to prevent out-of-bounds
list access, but this is not needed since null checks are already
performed after obtaining list members via BLI_findlink().

In addition, leaving indices zero-initialized facilitates use of the
Python API, for example when displaying action map information in a
UI list.
