feat(colcon-build): use nice command to not overuse resources

[xmfcx]

Description

nice is part of GNU coreutils, let's you run a program with modified scheduling priority.

Comes bundled in the our Ubuntu containers.

This PR aims to utilize it to prevent colcon build from overusing the runner resources.

man page

Run COMMAND with an adjusted niceness, which affects process scheduling. With no COMMAND,
print the current niceness. Niceness values range from -20 (most favorable to the
process) to 19 (least favorable to the process).

I set the default to be 19 in this PR.

Original default was 10.

Failure example for a runner due to over-usage of a machine during colcon build:

• https://github.com/autowarefoundation/autoware.universe/actions/runs/10419516744/attempts/1

  build-and-test-codebuild (humble, -cuda)
  The self-hosted runner: ed3beb09-f7b2-47dc-a3e2-f94fed279d09 lost communication with the server. Verify the machine is running and has a healthy network connection. Anything in your workflow that terminates the runner process, starves it for CPU/Memory, or blocks its network access can cause this error.

Tests performed

• Build was successful:
  • https://github.com/autowarefoundation/autoware.universe/actions/runs/10450884453/job/28936135748
  • test failed but it's a known issue, not related to this.

Even with the nice command,
https://github.com/autowarefoundation/autoware.universe/actions/runs/10454375310/job/28946832098?pr=8498

this one has lost connection due to resource overuse.

Machine had 15GB RAM and 8vCPU and 0 swap.

Added a specs step for these: https://github.com/autowarefoundation/autoware.universe/actions/runs/10454375310/job/28946832098?pr=8498#step:5:1

We can still merge this but I will create another PR that enables user to set parallel workers or makeflags
