Use common uuid generator everywhere

[msujew]

What it does

Since merging #12935, we now have a native way of generating UUIDs instead of relying on the uuid package directly. With #13082, this generator has been used a lot in @theia/core. This change aligns the whole repo with this decision and removes all usage of the uuid package in Theia.

How to test

CI is green, manual smoke test is successful. Nothing should have changed in the behavior of the app.

@msujew we still seem to require the uuid types package in some package.json files: "@types/uuid": "^7.0.3"

In #13265 I am currently using uuid v5 to generate a hash that is an uuid.
My suggestion would be to add this uuid hash method in the theia common package as well like this: 63efe7a
However we would have to keep the uuid dependency on the core package then.
I will rebase my PR on this one once merged.
Would this be fine for you?

@jfaltermeier I would recommend the reverse; Please merge your PR first and then I'll rebase :)
