Core: Introduce PDF Import-Export dialog (#20860)

Browse Source 
* Core: Introduce PDF Import-Export dialog

Currently, we only have hardcoded exporting to one pdf version, which
leads to (as in one of the below issues) to problems, such as
non-transparent layers, which are by default not supported in PDF/A-1b.

So, this patch adds an option to the user to select their preferred PDF
version by introducing new dialog under Import-Export in Preferences,
and allowing to update that version before exporting.

* Core: Add informational messages regarding selected PDF format

* Gui: Handle Qt < 6.8 unsupported PDF format

* Gui: Switch PDF export prefs dialog to use tr()

* Gui: Remove center alignment of PDF version description
