Get rid of StaticArrays

[SimonDanisch]

And some other type clean ups.

This doesn't seem like the correct long term solution if we can cache precompiles between modules in 1.8+.

Xref discussion from a while back: #91

if we can cache precompiles between modules in 1.8+.

That's not helping, since StaticArrays emits much harder code to compile...So until we cache binary, this is a valid approach.
I'm keeping the interface mainly the same, and this also helps remove complex code to wade through while optimizing Makie's compile times - while still allowing us to switch back to using StaticArrays once it makes sense.

Benchmarks indicating the utility of this PR are done with Julia already caching between modules. Since the new code is much less complicated it does indeed shave off around 1-3s.

See: MakieOrg/Makie.jl#1701
But yes, this opens up the discussion from #91. Since I'm touching all the Vec code, I'm willing to overthink the Vec/Point interface :)

This does share some time off Plots also:

julia> @time using Plots
  3.701392 seconds (6.20 M allocations: 496.627 MiB, 4.59% gc time, 21.38% compilation time)

julia> @time using Plots
  3.452578 seconds (6.12 M allocations: 487.336 MiB, 4.05% gc time, 22.26% compilation time)

Added some suggestions around StaticArraysCore.jl

[hyrodium]

We now have StaticArraysCore.jl, so this definition can be removed.

Suggested change

	using Tables, StructArrays, IterTools, LinearAlgebra
	using StaticArraysCore, Tables, StructArrays, IterTools, LinearAlgebra

I'm going to close this for now.

1. Compile times are pretty good with package images
2. We started re-implementing large parts of staticarrays, which seems better spend on improving StaticArrays compile times itself
