[fx][format-code] Allow only changed lines to be formatted.

ClangFormat supports specifying which lines should be formatted. Add
support for this in "fx format-code" by adding an option
"--changed-lines" which detects  which lines have been changed in the
file (relative to the git base), and plumbs these through to
clang-format.
