DDS: Fix loading files without DDSD_CAPS or DDSD_PIXELFORMAT

Main: Ensure existing of user data dir in `setup()`

Remove 'de_CH' translation (4% complete) to default to the 100%
complete 'de' one.

Fixes #32625.

(cherry picked from commit 35a5ebb44d534683da4e2e6b774fe7e1d165a24b)

When it was in `setup2()`, it would arrive too late for the optional file
logging feature.

Fixes #32488.

GDScript LSP: Fix wrong error checks added in #39385

Add note about automatic window title to FileDialog documentation.

MSDN says:

> When you write .dds files, you should set the DDSD_CAPS and
> DDSD_PIXELFORMAT flags, and for mipmapped textures you should also
> set the DDSD_MIPMAPCOUNT flag. However, when you read a .dds file,
> you should not rely on the DDSD_CAPS, DDSD_PIXELFORMAT, and
> DDSD_MIPMAPCOUNT flags being set because some writers of such a file
> might not set these flags.

Fix TabContainer emitting spurious tab_selected signals when a theme …

Reverts `latest_client_id` back to 0, as I misunderstood how the client
IDs are assigned and, without further testing and debugging, I can't
say if this was a bug or a valid default value.
Similarly, a `latest_client_id` of -1 is no longer raising an error.

Fixes #39548.

- The repaint code was moved outside of set_current_tab() and to a "_repaint()" private function
- _on_theme_changed() will now only call _repaint() and update()
This means _on_theme_changed() will do only what it needs (repainting the TabContainer to account for the new theme)
