feat(v8/scripting): swap from msgpack-lite to msgpackr

[thelindat]

Goal of this PR

Swaps out the outdated and unsupported msgpack-lite package for msgpackr, improving performance (58-95% faster depending on data and size) and adding support for more features (some are disabled for compatibility purposes).

How is this PR achieving the goal

Swaps out the custom version of msgpack-lite with msgpackr, adds bufferish to maintain backwards-compatibility for unknown types, and uses some patches to behave more like msgpack-lite.

This PR applies to the following area(s)

Might be worth only disabling moreTypes for sessionmanager-rdr3, and adding a metadata the resource can define to turn off moreTypes and check if its set with https://docs.fivem.net/natives/?_0x964BAB1D

[thelindat]

Perhaps in a separate PR which can enable moreTypes and also add some extensions that are "breaking" (e.g. vectors to array or a builtin vector class) - rather than moving the goalpost here?

Few things to improve:

1. Add licenses, links to original and authors mentions to the files containing third-party code (as it was with msgpack-lite).
2. Document any changes made to the third-party code so that when such code would need to get changes from the upstream - we'd know what changes to re-apply.

Nits:

• main.js is not the most well "styled" code for sure, but it'd be great not to worsen it and keep using trailing semicolons and commas along with proper indentation for our code (third-party excluded, of course).

[thelindat]

Licenses and links added to the built files, including a link to my fork of msgpackr so you can see the commit. I made sure to comment out the original code and include a note about msgpack-lite above the modified code; but it's fairly minimal. Some parts might not even be strictly necessary - but better safe than sorry.

I'm using the msgpackr global that's already exposed by the library, which is now removed to prevent any funny business.
msgpack_packr is removed since it doesn't serve much purpose, and I've exposed addExtension as msgpack_extend for clarity and consistency.

Good stuff!

The original reason packr was exposed was because msgpackr supports structures, see this section, and you can add them via the packr object (iirc)
