[Refactoring] Update id naming convention

[klakhov]

Motivation and context

For a long time we now have been using *ID naming convention for id variables, but in some code that was added before this, some variables keep *Id naming convention. This PR tries to unify it.

How has this been tested?

For a long time we now have been using *ID naming convention

First of all, I can't remember any discussions regarding naming conventions.

Anyway, we may follow Id, or ID, it is discussable (chat GPT recommends using resourceId BTW as it corresponds to camel case. However I would split that patch into two:

1. Renaming just variables, easy to review
2. Renaming object properties, class properties, etc. This change will break something in enterprise repos or something untested and needs to be reviewed carefully.

Patch needs to be reworked, I will close it for now till I have time to finish it
