Improve Issues

[ffreyer]

Description

Similar to #4108, this pr aims to make some improvements to our Issues (and Discussions) infrastructure. Feel free to give your opinions and suggestions.

Some general thoughts:

• Issues should be actionable, i.e.
  • not be question, loose feature requests, planning or other open ended posts. Those should be Discussions
  • they should deal with one (preferably small) problem. So no roadmaps or other kinds of issue collections (Again, Discussions)
  • not be so old that their validity is unclear (but this is for issue cleanup)
• duplicates should be closed in favor of the first such issue
• We should take labels more seriously to make it easier to find specific issues. E.g.
  • tag what is affected, i.e. Makie/GLMakie/WGLMakie/CairoMakie/RPRMakie (maybe github docs, CI?)
  • tag the type of issue, i.e. bug/regression/documentation/enhancement
  • categorize issues by problem groups, e.g. plot attributes, rendering, DataInspector, transformations, 2D/3D
  • remove labels that are not applicable or have few related issues, e.g. dependencies, naming, planning, question, vizcon, GeometryBasics

I'm planning to go through all the open issues at some point and close the ones that are too old to act on and add tags as I go. I think after that it'll be clearer what's actually useful to have there.

Compile Times benchmark

Note, that these numbers may fluctuate on the CI servers, so take them with a grain of salt. All benchmark results are based on the mean time and negative percent mean faster than the base branch. Note, that GLMakie + WGLMakie run on an emulated GPU, so the runtime benchmark is much slower. Results are from running:

using_time = @ctime using Backend
# Compile time
create_time = @ctime fig = scatter(1:4; color=1:4, colormap=:turbo, markersize=20, visible=true)
display_time = @ctime Makie.colorbuffer(display(fig))
# Runtime
create_time = @benchmark fig = scatter(1:4; color=1:4, colormap=:turbo, markersize=20, visible=true)
display_time = @benchmark Makie.colorbuffer(fig)

	If this is about something that worked in an older version of Makie,
	please file a regression report by going back to the issue page
	and selecting the "Regression" template.

Might also be a good idea to have
```julia
# Your code here
```
as part of the templates for people that are new to the syntax
