fix(vm): remove sequencer usage from createVmThreadsPool function (fix #4637)

[mhogeveen]

Description

--pool=vmThread in combination with --shard=1/x skips test files. This is due to unnecessary code remaining in the createVmThreadsPool function after a refactor where the Sequencer was refactored to be outside of pools.

This PR removes that code.
