next-assembly-info-files

[njlr]

This PR adds a new attribute to the DotnetAssemblyInfo provider called files, which is all of the files in the package. This is ground-work for building a rules_fable.

Fable will attempt to "crack" a Nuget package by starting from a referenced DLL and walking up the directory tree till a nuspec file is found. Then it will try to collect any fs, fsi and fsproj files in that sub-tree. To support Fable without major modifications, it is easiest to give all package files as inputs to the Bazel action.
