fix!: autocompletion window components alignment

[lopi-py]

Before

After

I have a custom windows.autocomplete.draw function:

draw = function(ctx)
  return {
    {
      ctx.item.label,
      ctx.kind == "Snippet" and "~" or nil,
      fill = true,
      hl_group = ctx.deprecated and "BlinkCmpLabelDeprecated" or "BlinkCmpLabel",
    },
    " ",
    { ctx.kind, hl_group = "BlinkCmpKind" .. ctx.kind },
  }
end

Notes

• I've removed windows.autocomplete.min_width and windows.autocomplete.max_width since it's way easier to maintain the alignment without those, but in compensation, max_width component option was added:

draw = function(ctx)
  return {
    {
      ctx.item.label,
      ctx.kind == "Snippet" and "~" or nil,
      fill = true,
      max_width = 5,
      hl_group = ctx.deprecated and "BlinkCmpLabelDeprecated" or "BlinkCmpLabel",
    },
    " ",
    { ctx.kind, hl_group = "BlinkCmpKind" .. ctx.kind },
  }
end

Also it feels weird to have unnecessary blank spacing with the windows.autocomplete.min_width option

• This PR allows for multiple fill components
• Added padding for both left and right sides of the display item

Great work! The multiple fills and max_width especially make layouts much easier. One small change, a rebase and I'll merge

[lopi-py]

I had fun with git 🥹.
It should be ready now @Saghen, also would you accept a PR to add snippets indicators and the draw function I made?

[Saghen]

Yep I would, should they be at the beginning instead?

[lopi-py]

It feels like its missaligned with the other items, actually, the snippet indicator is taken from nvim-cmp

Thank you!
