reformat about_flags

In the about_flags.cc file we have a large, single statement that spans ~1900 lines.  Touching this statement and running clang-format causes the statement to be reformatted, which is often a much larger change than desired.

Note: there should be no functionality change in this CL.  This is a reformatting change only.
