Use CMake to update translation files

Browse Source 
It uses lupdate directly.
Qt's `qt_add_lupdate()` cmake function doesn't help much.
First of all it is Qt6 only.
Secondly, our project is split into multiple targets but we need all
strings into a single .ts file per language.
Thirdly, it looks like it will skip source files that are added conditionally into the build
via cmake condition checking (eg DBUS source files). We need to gather all strings present
in the source files regardless of the build configuration.

On another note, this is a step towards reducing dependency on qmake/autoconf.
