Add basic sync for PvP

[tornac1234]

• [x] Basic sync for PvP (only allowed with knifes and heatblades for now)
• [x] ~~Maybe: add sync for propulsion and repulsion cannon~~

To be tested (and merged) upon #2106 (won't work without it)

is there really one who likes pvp in Subnautica? if one wants pvp, why not go ahead to play pvp games? there are tons of such games. i don't think core players of Subnautica are interested in pvp.

Most multiplayer games have ways for players to damage each other. Even if it's not the main focus of the game, it gives players more options to have fun with their friends. Having a last man standing battle within a large base or picking people up and repelling them far away with the propulsion cannon is the kind of thing people (like myself) like to do with our friends. I don't think the argument of "if you want to do PvP, play a PvP game" is a good reason to stop this.

Besides, you can just turn PvP off in the configs if you don't want it.

Waiting for #2106 to be merged, then this will get some tests and will be ready to be merged
