YT-19456: JobController config refactor pt.2 JRM now has its own config

Configs diff:
New config path ```"job_resource_manager"``` has been added to the cluster node configs (both static and dynamic). Following options were moved there from ```"exec_node/job_controller"```:
```"resource_limits"``` -- static
```"cpu_model"``` -- static
```"start_port"``` -- static
```"port_count"``` -- static
```"port_set"``` -- static
```"cpu_to_vcpu_factor"``` -- static and dynamic
```"enable_cpu_to_vcpu_factor"``` -- dynamic
```"cpu_model_to_cpu_to_vcpu_factor"``` -- dynamic
```"profiling_period"``` -- copied to dynamic, not moved
```"memory_pressure_detector"``` -- dynamic
```"mapped_memory_controller"``` -- dynamic
```"free_memory_watermark"``` -- dynamic
