Fix per character attributes in text

[ffreyer]

Description

This example currently throws an error which is fixed by this pr:

using GLMakie
f = Figure()
ax = Axis(f[1,1])
text!(ax, "ab", position = (0.00, 0.85), color = [:red, :blue], textsize = 34,
        align = (:left, :bottom))
f

This happens because

https://github.com/JuliaPlots/Makie.jl/blob/bfe128ee1535ad75a4bab6109826caa08ba5f4de/src/basic_recipes/text.jl#L34

generates a 1:1 range for strings which is incompatible with the length two color vector. Afaik all the per character stuff happens in glyph_collection (or layout_text) so I just added a branch without the broadcasting for text::String. This seems to work fine for scalar and vector inputs or text and latex text.

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))
