  Update for SDL3 coding style (#6717) I updated .clang-format and ran clang-format 14 over the src and test directories to standardize the code base. In general I let clang-format have it's way, and added markup to prevent formatting of code that would break or be completely unreadable if formatted. The script I ran for the src directory is added as build-scripts/clang-format-src.sh This fixes: #6592 #6593 #6594 (cherry picked from commit 5750bcb174300011b91d1de20edb288fcca70f8c)
