Export Selection: the picked format's options dialog follows the save panel

document.exportSelection run with no params or {} (a shortcut, or an
automation call) wrote the picked file straight away with each format's
defaults: a PDF used the default preset, so Save PDF's options, such as
writing long pages in points, could not be chosen. It now takes Export
As's route after the save panel: Save PDF without its Artboards
section, SVG Options without its artboards, the raster options, EPS
Options, DXF Options, Text Export Options with Selection Only on, or an
exporter plug-in's parameters. OK writes the selection alone, cropped
to it, with the chosen options. While a dialog is open the call returns
null, and OK returns what file.exportAs returns, without format or
bounds.
With a path or any option it still writes straight away.

- file.exportAs takes exportSelection: true and then writes the
  document that document.exportSelection writes
  (fileio::selection_doc), without artboard choices. The options
  dialogs and the replace-file questions pass it on.
- Nothing selected stops before the save panel.
- SVG Options opened by Export Selection leaves the remembered Use
  Artboards as it was.
- Exports through file.exportAs (Export As and the options dialogs)
  apply Appearance of Black's rich black, as document.export does.

A settings block that VectorCraft can't read (malformed, another effect's, a value out of range or a key it doesn't know) keeps the object's drawn look (part of #637; [raster effects reference](https://helpx.adobe.com/illustrator/desktop/special-effects-styles/apply-filter-effects/raster-effects-reference.html), [Photoshop File Formats Specification](https://www.adobe.com/devnet-apps/photoshop/fileformatashtml/), [scripting the filter gallery](https://community.adobe.com/questions-712/scripting-support-for-the-filter-gallery-1064646); `crates/eps/src/import/ai/style/tests.rs`, `crates/eps/src/import/ai/tests.rs`).
     PDF export and `.ai` saves write a page with a side longer than 14,400 pt with a `UserUnit` (PDF 1.6), its longer side divided by 14,400 and rounded up to the next thousandth, so that no side is longer than 14,400 units (ISO 32000-1, Annex C.2); a PDF 1.5 file with such a page is written as PDF 1.6 with PDF 1.5's encryption, PDF/X files and PDF 1.3 and 1.4 files write it in points (in PDF 1.3 and 1.4, a page past 32,767 pt that needs a real number past 32,767 is refused with an error naming it), a page whose short side is 3 pt or longer but would be under 3 units at that `UserUnit` gets a smaller one that keeps the short side at 3 units, and the export's warnings give each such page's size and how it is written (#6382). The Save PDF dialog's "Write pages longer than 200 in at full size in points" (`longPagesInPoints`, on by default; `.ai` saves leave it off) writes such pages in points without a `UserUnit` at every PDF version, in files without a PDF/X or PDF/A standard, so readers that ignore `UserUnit` show them at full size.
