Add launch_3 and launch_heavy_3

[jackpot51]

I'm not sure if this has everything required, but it works to show these boards in the configurator. Please do a thorough review.

meta.json files seem to be correct, other files match launch_1/launch_2 and launch_heavy_1 as expected.

I've been meaning to de-duplicate things here so the same keymap.json files could be shared by all QMK boards and all EC boards, and launch_1/launch_2/launch_3 could have the same files in keyboards (which should also help with #139).

But this is right for how things currently work, assuming testing goes as expected.

@pop-os/quality-assurance any thoughts on this?

Somehow I missed this, sorry about that. I'll look at it today.

[ids1024]

This will need to be updated slightly for the changes in #208. I can do that.

[jackpot51]

That would be helpful, @ids1024. Thanks @leviport

Okay, rebased, added the is_qmk field to meta.json, regenerated with layouts.py, and removed the files that are no longer needed.

layouts.py didn't change anything except layouts/keyboards/system76/launch_heavy_3/leds.json. Looks like the LED mapping has issues though. But it's different than launch_heavy_1, so I'm not sure exactly what would be correct: system76/qmk_firmware#35 (comment).

Edit: Or actually, do they match launch_heavy_1, and I was looking at the wrong thing? Then that shouldn't be a hard fix.

[ids1024]

Updated system76/qmk_firmware#35 and this to use LED mapping that should be correct.

I'm not sure if it's because of this PR or the firmware itself, but setting LEDs is not persistent across unplug/replugs. I can set the LEDs differently, but unplugging the keyboard and plugging it back in results in the default Spacetime LED pattern. Key binding changes still persist as expected, however.

[jackpot51]

@leviport that would be firmware.

[leviport]

Since the LED bug is due to firmware, I think this update is good to go. --launch-test mode is working, keymap importing/exporting is working, and I can assign keys and LEDs on launch_3 and launch_heavy_3. Quick regression testing on launch_lite_1, launch_1, and my oryp9's bulit-in keyboard also went smoothly.

@ids1024 can you do an engineering review?
