Bazel client: implement directory tree walking

This change:

- merges the //src/{main,test}/cpp:file and
//src/{main,test}/cpp:file_platform libraries
because "file" and "file_platform" need each other
and this makes logical sense anyway

- implements a function in file_<platform> to run
a custom function on every child of a directory

- implements a function in file.cc to recursively
traverse a directory tree, based on the previosly
mentioned function

- removes the corresponding logic from the Bazel
client to make it more portable
