breaking release v0.18

[SimonDanisch]

TODO

• [ ] wait for all changes to get merged (timed release?)
• [ ] make sure NEWS.md mentions all changes, has good enough guides for upgrading to new changes
• [ ] up versions
• [x] enable rebase & merge for the breaking-release branch, so that we don't squish all the merged PRs

Merged changes so far

• Don't use data_limits to figure out axis type #1770.
• Clean up conversion pipeline #1810.
• Clean up Attribute constructor & indexing code 1930.

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(display(fig))
