Current look of VSE timeline view strip transformation handles makes them
somewhat "too narrow", especially after recent changes that made them
more narrow than before (handle tweaking feature) and a strip visual change
that made strip outline not go outside of strip bounds. They are now just
2px wide, effectively.
This changes their look as outlined in #123332 design task:
- The inset dark line is no longer over the handles, but rather "inside"
of them (except when handles are semitransparent, i.e. for strips that
are not selected).
- The handles themselves have rounded corners.

Now the strip outline (1 point for unselected strips, 2 point outline +
1 pt dark inset) takes monitor DPI / user preference line width into
account, via the usual U.pixelsize machinery.

Somehow the 16K inside a string is parsed as being an integer, leading
to error messages about the `K` suffix.
```
ERROR (gpu.shader): gpu_shader_icon_multi VertShader:

| Error: C0159: invalid char 'K' in integer constant suffix
```
Fixed by changing the 16K to the actual number.

Strips still have sharp corners when you're dragging them from file browser and
switch to rounded when dropped. Fix by using the same drawing code (and shader)
as regular timeline drawing path.

VSE timeline strips now have rounded corners. Strip corner rounding radius is
4, 6 or 8px depending on strip height (if strip is too narrow to fit
rounding, then rounding is turned off).
This is achieved with a dedicated GPU shader for drawing most of VSE
strip widget, that it could do proper rounded corner masking.
