refactor(ChartData): move chart_data_apis from ChartRestApi ChartDataRestApi

[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 second PR
The next PR is #17405

PR description

Create new view - ChartDataRestApi in new module but inherit ChartRestApi
then moves all chart data endpoints to that new view so the view will be focused only on chartData

Test plans

There are no logic changes so new tests are not required
but in the next PRs, I'll split the API tests into new separate modules and classes
