refactor(minecraft): update to 1.21.6

[DataM0del]

This is going to take a while to even get it to compile due to SwordItem and ArmorItem being converted to data packs. I'm coming for you Mojang, get rid of data packs now!1111!111!!!!! (/j, might be useful for the sword blocking thing, but that's like the only 1 good thing about data packs).
I probably should've reopened the old PR (#5913), but yes. (best reasoning 🤑)
Mojang will probably make everything use a data pack, so we probably are best off at some point trying to make everything ready for data packs, since this is annoying.

• It launches (before 4eeac7a since we're updating again)
• MCEF works (never)
• Render shortcuts / etc are fully refactored to be reimplemented
• (port specific) TODOs are gone
• Fix player slowly drifting to the left (movement input issue thing? I think I mixed it up)

is there a todo tracker you have setup if so approx what percent way are you through on fully updating to 1.21.5

no, I'll make it now

[DataM0del]

I made it, also, I'm going to actually update it this time after I paste the lb legacy movefix into my client 🤑

So the new update works with 1.21.5?

not as of now

reading the todo on the github it only just seems to be able to launch but many stuff is still broken

[DataM0del]

1.21.6 is happening... 🥱
hopefully they reverted some of the 1.21.5 changes since, well, I don't want to waste all my time trying to fix MCEF 😡

they broke MCEF in 1.21.5 by removing some RenderSystem stuff and I had to replace it with GlStateManager stuff instead lol, also you can't tell it to register a abstract texture with a glId anymore, as that has been moved to GlTexture.
Maybe NativeImageBackedTexture might work?

[DataM0del]

1.21.6 has an input packet and now uses that for sneaking... no quake 2 movement system please 🙏

im guessing since 1.21.6 is wery close to here you are focusing your efforts on making it work with the newest version rather than keeping woriking on 1.21.5 and then updating again

uhh... no rofl. just hoping by updating it I can fix MCEF easier on that version 💀

[DataM0del]

replaced by #6303 since I'm lazy

[sqlerrorthing]

oh no :*

[vanvac]

replacement not complete give up

[sqlerrorthing]

you do a lot of work man 😞

[superblaubeere27]

We can make use of the work anyway, so it's not all for nothing. I take a look at your implementation to get a second opinion on what the correct port for certain things should be.
