feat!: allow multiple bindings and functions files

Where previously the document metadata could specify a single bindings
file, and a single functions file, it can now specify one or more. If
a single value is given, that's the filename. Otherwise, it can be a
YAML list of filenames.

Drop the functions_filename template variable, which was effectively
unused, and for which there is no recorded use case at this time.
