58031: util/log: delay the formatting of log entries r=itsbilal a=knz Needed for #58126 Prior to this patch, the logging events were converted to a `logpb.Entry` very early in the logging pipeline. This was forcing the conversion of the logging tags to a flat string too early, and making it hard for (e.g.) a JSON formatter to preserve the structure of logging tags. This patch averts this by introducing a new `logEntry` type which has more-or-less the same structure as `logpb.Entry` but keep the logging tags structured until the point the entry is formatted. Release note: None Co-authored-by: Raphael 'kena' Poss <knz@thaumogen.net>

Release note (cli change): It is now possible to set the `format` parameter of any log sink, including file sinks, to `json`, `json-compact`, `json-fluent` or `json-fluent-compact` to write entries as structured JSON. Refer to the linked reference documentation for details.
