feat: improve additional-settings-for-developers section

[xmfcx]

Description

Parent Issue:

• Update DDS isolation instructions for shared networks in Autoware #484

Some updates:

• Divide additional-settings-for-developers into multiple pages to increase readability and maintainability.
• Marking export ROS_LOCALHOST_ONLY=1 as a useless act and also telling users to remove it if they've enabled it since it causes problems when cyclone dds is set to use lo.
• Add more cases where setting a ROS_DOMAIN_ID may fail (e.g. launch_testing utilizes random domain ids to isolate within a machine)
• Improve DDS tuning section
  • Make default interface as lo instead of autodetermine=true
  • Add all recommended dds stuff here
  • Link it from the installation instructions as these are very important, without these, Autoware never works as expected.
• Update links within the documentation to changed pages
• Add google test color option to console settings page
  • Update the broken link on the same page

I've went through the pages many times to make sure everything is well connected and also made sure there are no broken links.

• Unrelated broken link is fixed by fix(directory-structure.md): update broken link #590

I've looked into the pages from the perspective of both junior and experienced Autoware developers and made sure they all can benefit from the information.

I hope you like the changes too.
