update format.sh (#6240)

* update format.sh

add shellcheck to format.sh
add statement macros to .clang-format
add no clang format to format.sh
add changed file list to format.sh diff
rename --cf-version to --print-version in format.sh
lint files

* enable --shell on ci runs

* remove useless semicolons

removes the semicolons after empty function definitions
these semicolons are optional, they don't do anything
this will have functions be consistently formatted
if we want to keep the option to have these on the same line like they
were before we should use the option AllowShortFunctionsOnASingleLine: None

* fix script

* update echo line in lint_cpp.sh which doesn't lint cpp only at all
