Defibrillator Hotfixes

Unable to reproduce https://github.com/tgstation/-tg-station/issues/5664. Possibly fixed here because it was related to the 'dropping wielded paddles' issue that can only be reproduced on the server but not locally.

- Removed RNG for defib since reviving has a very specific criteria anyway and failing despite meeting that isn't very fun.
- Having -180 burn or brute damage (a traitor wailing on you with an esword or revolver until you die for example) will cause reviving to be completely blocked and fail.
- Defibs now heal 5 of each standard damage type so unless you have SEVERE brute or burn (-180) you will be able to be revived. This fixes the 'get revived but immediately deathgasp' issue with standard damage values.
- Armor and space suits block defibbing entirely.
- Changed the on = !on toggle var setting back to normal because I'm stupid and didn't really understand it until now.
- POSSIBLY fixed the error where dropping wielded paddles breaks them. I CANNOT encounter this error on my local server testing at all so I'll have to give this a post-update test after it's done.
- Fixed noclone check breaking the revive process.
