chg: dev: Update clang-format style with options added in newer versions

Add and apply InsertBraces statement to add missing curly braces around one-line statements and use ControlStatementsExceptControlMacros for SpaceBeforeParens to remove space between foreach macro and the brace, e.g. `FOREACH (x) {` becomes `FOREACH(x) {`.

Merge branch 'ondrej/update-clang-format' into 'main'

See merge request isc-projects/bind9!10863
