Update clang-format rules

[randombit]

Not going to do this anytime soon, best to wait for when things are quiet in terms of active PRs. Maybe end of the year around holidays? This is just to track/discuss possible changes. It would be best to make any such changes all at once to avoid churn.

• Change AllowShortFunctionsOnASingleLine from Inline to Empty
• Change AllowAllArgumentsOnNextLine from true to false
• Change AllowAllParametersOfDeclarationOnNextLine from true to false

As with any rules based formatter, sometimes the result of any change is worse formatting vs what was before, but overall I think these would lead to more readable code.

By EOY Github Actions should have Ubuntu 24.04 available and we could consider switching from clang-format 15 to clang-format 17 at the same time.

If we are able to upgrade clang-format

• BreakAfterAttributes = Always
• BreakBeforeInlineAsmColon = OnlyMultiLine
