move GeometryBasics to Makie requires block

[ranocha]

I looked at the load times and latency issues with Julia v1.9 beta. Using the branch JuliaLang/julia#48075, this reduces the time of using Trixi for me from

julia> @time @eval using Trixi
  9.252053 seconds (19.39 M allocations: 1.462 GiB, 5.46% gc time, 28.00% compilation time: 36% of which was recompilation)

on main to

julia> @time @eval using Trixi
  8.004904 seconds (17.29 M allocations: 1.301 GiB, 5.61% gc time, 24.59% compilation time: 24% of which was recompilation)

on this branch.

As far as I can tell, the functions I moved are not called outside of the Makie recipes stuff. We lose the ability to use specify compat bounds on GeometryBasics.jl in this way, but I hope this is no problem. This could be solved/improved in the future with conditional dependencies introduced in Julia v1.9, see https://pkgdocs.julialang.org/dev/creating-packages/#Conditional-loading-of-code-in-packages-(Extensions)

What's your take on this, @jlchan ?

Nice find! I like this fix - reducing the number of independently loaded packages makes sense, and it makes it more clear that GeometryBasics is just used with GLMakie.

Great work! Will there be similar opportunities for other packages?

I'm looking into it

@sloede: Here you are jlchan/StartUpDG.jl#73 (but is is not as pronounced as the result here)
