1. bevy_log: upgrade to tracing-tracy 0.10.0 …

   This upgrade should bring some significant performance improvements to
   instrumentation. These are mostly achieved by disabling features (by
   default) that are likely not widely used by default – collection of
   callstacks and support for fibers that wasn't used for anything in
   particular yet. For callstack collection it might be worthwhile to
   provide a mechanism to enable this at runtime by calling
   `TracyLayer::with_stackdepth`.
   
   These should bring the cost of a single span down from 30+µs per span to
   a more reasonable 1.5µs or so and down to the ns scale for events (on my
   1st gen Ryzen machine, anyway.) There is still a fair amount of overhead
   over plain tracy_client instrumentation in formatting and such, but
   dealing with it requires significant effort and this is a
   straightforward improvement to have for the time being.
