clang-tidy: apply modernize-loop-convert over a set of files (#23443)
* Modernize using: ``` ./scripts/run-clang-tidy-on-compile-commands.py --checks modernize-loop-convert --compile-database out/linux-x64-chip-tool-clang/compile_commands.json --export-fixes out/fixes.xml fix ``` * Fix using: ``` ./scripts/run-clang-tidy-on-compile-commands.py --checks modernize-loop-convert --compile-database out/linux-x64-all-clusters-clang/compile_commands.json --export-fixes out/fixes.xml fix ``` * Modernize using: ``` ./scripts/run-clang-tidy-on-compile-commands.py --checks modernize-loop-convert --compile-database out/linux-x64-tests-clang/compile_commands.json --export-fixes out/fixes.xml fix ``` * Restyle and remove unused variable * Remove more unused variables for array sizes * Restyle * Start some manual renames of iteration values ... automated tool is quite silly * More manual updates for naming of things. Code should be cleaner now * Restyle * Enforce lowercase naming for cdSigningKey iterator variable * One more pass for cleanups Co-authored-by: Andrei Litvin <andreilitvin@google.com>
