logging: better use of log::Entry internally #34865

   Preparatory work to enable struct-based logging for kernel (#34374), but I think it’s a mild improvement by itself too.

   #34465 introduced util::log::Entry. This PR updates some internal functions and structs to make better use of that new plumbing.

   Mostly a refactor, although ddfc66071a86bedc4b81096174e39df0b116e1d2 can very slightly affect the log’s timestamp.

5. logging: pass log::Entry through to logging functions

   Use the entry's timestamp and thread_name, captured at the call
   site, instead of re-capturing them in the logger.

7. logging: replace FormatLogStrInPlace with Format

   Return a new string built left-to-right instead of mutating one
   with repeated insert(0, ...). Take a const log::Entry ref since
   both call sites now have an Entry available. Also move
   LogEscapeMessage inside so callers don't need to pre-escape.
