Revert raw history changes (#7314)

- **Revert "Fix history batch validations (#7281)"**
- **Revert "Send raw history blobs from history service to frontend
(#7179)"**

## What changed?
Revert the changes for returning raw history event from history to
frontend.

## Why?
Some logic is moved from history to frontend handler. This might cause
issues during upgrade.
I will push a change to first copy these operations to frontend. Once
that change is released, I will reapply this change.

## How did you test it?

## Potential risks

## Documentation

## Is hotfix candidate?
