Parallelise GraphQL document validation

[MohamedSabthar]

Description:
The current implementation of the graphql uses an array of visitors to validate the graphql document.

Tasks

• Find the dependency between validator visitors (dependency graph)
• Group the validators that can be executed in parallel by multiple workers
• Check for performance improvement by comparing the load-test results

Describe your problem(s)
Each visitor is executed in sequence since the execution of some of these visitors depends on the previous visitor.

Describe your solution(s)
These visitors can be grouped by analysing the dependencies and executed parallelly to improve the performance.

Due to this intermittent failure, unable to compare the performance with the load test. Deprioritizing this task until issue #38047 gets fixed.
