[chore] Automatically split attribute tables based on deprecation status

[thompson-tomo]

Changes

This splits the attribute tables based on the deprecation status.

This provides the following benefits:

• deprecated attributes no longer needs to be moved to seperate groups simplifying process and improving history
• The attributes on signals are grouped the same as the registry
• The deprecated tables can have a different structure with links to new attributes

Outstanding tasks:

• consolidating deprecated attributes in to main file
• Putting informative briefs back on attributes rather than deprecation reason.

Note: if the PR is touching an area that is not listed in the existing areas, or the area does not have sufficient domain experts coverage, the PR might be tagged as experts needed and move slowly until experts are identified.
