support "any" graphic device

- shift temp-file generation from time-based to 'tempfile()', reduces
  the (slim) possibility of same-name images being created (e.g.,
  parallel production, fast rendering)
- add some graphic helper funcs for generalizing things across all
  'spec_*' plotting functions: is_svg, dev_chr, and graphics_dev
- add 'make_inline_plot' to centralize formation of the
  'kableExtraInlinePlots' object; prepend 'file:///' to paths when not
  is_latex, fixes display of some raster graphics; added "list" as a
  secondary class
- add 'listify_args' to enable any single-plot function to be able to
  vectorize any of its arguments (so that different plots on different
  rows can have different arguments)
- update 'spec_plot' to use these mechanisms
