[clang-format] Make sure rst documentation matches comments

clang/docs/tools/dump_format_style.py is used to read the comments
from clang/include/clang/Format/Format.h and update the contents of
clang/docs/ClangFormatStyleOptions.rst

Recent changes made these out of date. This commit syncs them by
folding the improved wording back to the comments and then
regenerating the rst file.
