octave-x: enable qt gui

[licy183]

Ref: #21868

[truboxl]

Actually been want to ask why 2 octave-x in x11-repo and TUR?

[twaik]

Octave in tur is built with custom toolchain so it can be built for 32 bits too.

[twaik]

In the case if you flip the gui toggle you should fix description because it mentions 'only cli'.

I will merge it in 48 hours if there is no more review or when it gets 2+ approves. Thanks!

[twaik]

Should not you mention qt6-qttools-cross-tools in build dependencies in the case if regular qt6-qttools is used or it is not required?

[twaik]

LGTM.

It is better to add it to build dependencies. But actually our building system will always fetch full dependencies, so if qt6-qttools is added in dependencies, qt6-qttools-cross-tools will be fetched too.
