Will this list of files be a burden to maintain?  Should we have a GN variable
for this list stored in the Dart repo?  Can we encapsulate these files in a GN
source_set?

It shouldn't be a burden to maintain (the list of sources has been stable for a
long time now). Regardless, I've added a new source set which is built by
applying a custom filter to two .gypi files in the Dart tree.
