VSE: Add Overlay popover panels

Add panels with overlay settings for strips and preview and overlay
enable/disable button.

Entries from the View menus moved to the overlay panels, which will
simplify cluttered View menus.

Additional options have been added:
- Strip Name
- Strip Source(ex. path)
- Strip Duration

So users can now select what info they need to see on the strips. When
No text is displayed, waveforms are drawn in full height.

VSE: Paste strips after playhead by default

Paste copied strips after playhead, because this is more intuitive.

Previous functionality is still available by enabling "Keep Offset"
property, or under shortcut Ctrl+Shift+V.

VSE: Reorder Tools in Sequencer/Preview

When in Sequencer/Preview mode, the Sampler was on top, which normally
is the place of Select, and Annotation seems to be after Sampler in the
bottom in the various editors.

GPencil: Improve interpolation of strokes with unequal lengths

Use the BKE_gpencil_stroke_uniform_subdivide function to subdivide strokes
before interpolation. When the target/source stroke is smaller than the other
stroke, it is subdivided until the lengths match. This improves the overall quality
of the interpolation of different sized strokes.

GPencil Array - Add option for uniform random scaling

This patch adds the option to make the random scaling from the grease pencil array modifier uniform.
The current settings allow a separate value for each of the 3 scaling axis. The modifier also creates different seed values for each axis so there is no way to keep the random scaling uniform.
This patch creates 1 random seed value and applies it to each of the scaling axis.

Here is a demonstration of the previous behavior and the new optional behavior.

VSE: Move remove gaps operator logic to module code

Logic was broken into finding gaps and ofsetting strips.
Functions were modified so they work on explicitly defined seqbase,
so they can be used as python API functions.

Functional changes:
- Improve performance by calculating gap length and offseting strips
at once. Previously strips were offset by one frame.
- Calculate gap from start frame. Previously gap was considered only
inbetween strips.

Fix crash selecting custom asset preview from maximized File Browser

If Preferences > Interface > Temporary Editors > File Browser is set to
"Maximized Area", "Load Custom Preview" in the Asset Browser would crash
after selecting the file.

1e799dd26ec1e848 was important to get this issue fixed. This commit just
ensures the file-list is recreated correctly after closing the temporary
File Browser, so the custom preview operator can execute on valid
context.

Fix various issues with temporary, maximized File Browsers

If Preferences > Interface > Temporary Editors > File Browser is set to
"Maximized Area", opening a File Browser from a File or Asset Browser as
regular editor would cause some issues. For example after closing the
temporary File Browser, the regular browser would take over the file
path and display settings from the temporary one. This is because they
used to share the same area data.

Some similar issues may have happend with temporary image editors.

Now, this commit finally separates the space data of temporary maximized
editors from the regular ones. So the editor data is entirely
independent now, as it should be.

Sculpt: Fair Face Sets operation for Face Set Edit

This implements a mesh fairing algorithm and implements the fair
operations for Face Set edit. This edit operations create a smooth as
possible geometry patch in the area of the selected Face Set.

The mesh fairing algorithm is designed by Brett Fedack for the addon
"Mesh Fairing": https://github.com/fedackb/mesh-fairing, with some
modifications:

- The main fairing function in BKE_mesh_fair.h does not triangulate
the mesh. For the test I did in sculpt mode results are good enough
without triangulating the topology. Depending on the use and the
result quality needed for a particular tool, the mesh can be
triangulate in the affected area before starting fairing.

- Cotangents loop weights are not implemented yet. The idea is to
also expose the vertex and loop weights in a different function in
case a tool needs to set up custom weights.

This algorithm will also be used to solve the limitations of line
project and implement the Lasso Project and Polyline Project tools.
It can also be used in tools in other areas of Blender, like Edit Mode
or future retopology tools.

Fix T83504: Cancel trim operators when there is no geometry

The boolean solver crashes when there is no geometry in the mesh. Also,
using the trimming tools without a valid intersection in the PBVH will
make the orientation and position functionality of the trimming shape
not work, so this is the safer solution.

Fix T83201: Cloth brush performance regression

I moved this code to sculpt_cloth and refactored it to use a switch case

Blenloader: Add utility function to write double array

It makes sense to support writing double arrays just like floats.

Fix Adjust Last Operation popup for operators relying on button context

This was reported for duplicating particle systems, then using F9 to
enable the 'Duplicate Settings' option (see T83317).
In this case, the operator gets the particle_system from (buttons)
context and if none can get found will duplicate all settings instead.

The reason why none gets found here is that buttons_context() doesnt
have a valid path when called from F9/SCREEN_OT_redo_last, path is
cleared when global undo does a file-read which clears the path (see
lib_link_workspace_layout_restore). It can be recomputed though to be
valid even from redo_last (at least when in the Properties Editor).

This was likely causing other operators (relying on buttons context)
from the Properties Editor to fail as well.

Fix crash opening maximized File Browser from Asset Browser

If Preferences > Interface > Temporary Editors > File Browser is set to
"Maximized Area", opening a File Browser from an Asset Browser would
cause the new maximized editor to be an Asset Browser. Exiting it again
would crash.

This fixes the wrong behavior and the crash. There's still an issue with
exiting the editor again, it stays a File Browser then and doesn't go
back to being an Asset Browser. That's to be fixed separately.

Fix (studio-reported) broken handling of relative font paths.

`blf_dir_search` BLF util would not properly handle relative fonts not
found in pre-defined 'system fonts' directoriesi stored in
`global_font_dir` global variable.

Now it rebases relative paths to current .blend file location as
expected.

Note: the fact that VSE is setting font ptaths relative by default is
probably not actually desired, but this is another issue really. See
`BKE_sequencer_text_font_load` code.

Fix redundant declaration warning

Function was declared twice (caused by merge conflicts) which GCC would
rightfully complain about.
