[Feature Request] Under "Manual scan" please add these three systems to the list

Description

I have some Neo-Geo and CPS-I/II/III roms and I'd like to put them in separate playlists. Normally, If I choose "Scan folder" everything would be put inside a Finalburn Neo playlist but I prefer to have them separated in multiple playlists.
To make an example with Neo-Geo files, if I want to make a separate playlist I actually have to choose "Manual scan" and select these options:

• Content Directory: [path to the folder that is containing roms for the desired system]
• System Name: CUSTOM
• Custom System Name: "SNK - Neo Geo"
• Core: Finalburn Neo
• Scan inside Archives: ON
• Arcade DAT Files: [path to my own arcade DAT / XML file]
• Overwrite existing playlist: ON

Retroarch do already have proper icons and assets to manage playlists for Neo-Geo and Capcom CPS systems, but actually there's no way to select cartridge-based Neo-Geo or a CPS System playlist under "System Name":

Expected behavior

If I click on system name to choose a system for my playlist, I'd like to be able to find these three options listed as well:

"SNK - Neo Geo"
"Capcom - CP System I"
"Capcom - CP System II"
"Capcom - CP System III"

Actual behavior

Actually there's no official support for these four playlists under retroarch, so I have to choose "Custom" and under "Custom System name" I have to manually write the name of these playlists. It's easy to do it on my computer, but not that easy when I use my raspberry or my Fire TV Stick with just a joypad.

Start by locating the Manual scan screen and the System Name list in RetroArch's frontend code, then inspect how existing playlist systems are defined. Done means the list offers SNK - Neo Geo and Capcom - CP System I, II, and III without requiring Custom naming, with the existing manual-scan options still working.
