feat(scripting/v8): implement vector classes

[thelindat]

Goal of this PR

Improve compatibility of vector types across scripting runtimes.

Note this is a technically breaking change to some scripts, as a few developers have opted to depend on undefined behaviour (i.e. implementation details).

How is this PR achieving the goal

Implements simple vector classes which can be correctly encoded and decoded with msgpack.

This PR applies to the following area(s)

ScRT: JS

Successfully tested on

You should implement quaternion too as it was supported before, ext type is 23 and it's the same structure as a vec4

Can do, but would also like to know how cfx prefer these implementations (just basic, or with methods?)
