Add NS to demos

[mvorisek]

fix #1199

Needed even if there is no autoloading on these, CS fixer otherwise behave differently without NS (and PHP too, as leading \ is not required otherwise for absolute names)

@ibelar, hi, you were refactoring these week or two ago... Can you check the changes and resolve the class names with the current CS settings?

I think you there are only two options

• extend the classes anonymously like $cl = new class() extends XXX {}; (so no need for actual/new class name)
• move them to a separate and equally names files

Then this PR is complete.

[DarkSide666]

@mvorisek please fix conflicts and then it's ready to merge.

[DarkSide666]

Not everything was finished here, but let's merge this in and if needed create new PR with additional changes in demo scripts.

@mvorisek - this did make demos harder to read. Their purpose was to teach others how to use features - but with anonymous classes it is a non-standard approach.

another consideration could be to assign dynamic classes into objects (drop get_class).

[mvorisek]

@romaninsh this is needed for CS to work - the only option is to separate the classes with proper autoloading.
