migrate supported console data

[Jamiras]

Updates to current wiki data, including some things that need to be updated there (like the current rollout consoles being supported).

Switched to bullet list (instead of table)

• Allows longer note texts
• Allows hyperlinking to individual consoles.
  • mkdocs also grabs these and allows an extra level of navigation in the sidebar
• Allows per-core information
• Can mark individual cores as supported/unsupported, even recommended. I tried to do this for most systems, but it could use some touch-up work.

Sorted by console name (instead of ID)

• Supported and unsupported consoles are no longer separated. Combined with sorting by name, makes it easier to find specific consoles.
