  Always use commit_id.py to generate commit.h
  
  commit_id_.py is capable of generating the default commit.h.
  This makes it so we always take a single path in gn.
  
  Remove the existing commit.h and generate it into the root
  generation folder (not the id subfolder) because Android blueprints
  can't handle generating into subfolders that don't exist.
  
  Make the <angle_dir> argument capable of taking a filename or
  directory name. This allows us to pass the .git/HEAD file which is
  a gn input.  Android blueprints require all paths used as input
  or output to a script are listed as inputs or outputs in the genrule.
