[Kotlin] Update gradle to 7.4.1 and simplify config files. (#7231)

* [Kotlin] Update gradle to 7.4.1 and simplify config files.

* [Kotlin] Add wrapper-validation-action to Kotlin Linux

* [Kotlin] Remove benchmark actions to reduce CI time

* [Kotlin] Move CI js test to Linux action, to increase Mac action speed

* [Kotlin] Generate gradle wrapper in order to be validate

Gradle wrapper from 3.3 to 4.0 are not verifiable because those files
were dynamically generated by Gradle in a non-reproducible way.

So they are now regenerated and will be checked using gitlab action:
gradle/wrapper-validation-action@v1
