Gettext addon: generate/update .pot file

[amezin]

Describe the problem

Weblate can update .po files, but .pot isn't updated

Describe the solution you would like

Weblate could run xgettext - like it runs msgmerge to update .po files.

Conventionally, the list of inputs for xgettext is kept in a file called POTFILES, or POTFILES.in. Build systems like Autotools and Meson expect that file, and most of the open-source projects you can find on GitHub do it this way. So there's no need to run the build system or custom scripts - only xgettext command itself.

Describe alternatives you have considered

Currently I have a custom GitHub Actions workflow that runs xgettext, commits and pushes the result.

Additional context

I'm going to work on this feature myself. But before wasting time on it, I want a confirmation that the idea is acceptable overall.
