refactor(QueryContext): add QueryContextFactory to meet SRP

[ofekisr]

Background

When we have worked on #16991 we wanted to test the new functionalities in concrete and accurate unittest.
All chartData flows and its components are too couple to superset so it is impossible to create unittests.
The flows are not testable and so many components do not meet the very important principle SRP and the code became so dirty

So I've started to refactor it (#17344 ) but many changes were added and it was hard to review so I decided to split those changes into small PRs so will be easier to follow

This is the tenth PR in a sequence of PRs to meet these
The next PR is #17496

PR description

Creating QueryContext is not only an assignment task, it contains some logic.
To meet the SRP, The creation task should be assigned to an external object.
After the PR the QueryContext constructor is decoupled from Superset so in the next PRs, the module can be decoupled from Superset

Test plans

There is no logic added so new tests are not required
