Replace tracing with bevy_log in bevy_render

[natepiano]

Objective

Replace direct tracing dependency with bevy_log in bevy_render for consistency with other bevy crates.

This was split out from #22649 at @IceSentry's request.

Solution

• Add bevy_log dependency to bevy_render
• Replace all use tracing::* imports with use bevy_log::*
• Remove tracing dependency from bevy_render
• Add event to bevy_log's tracing re-exports (needed by renderer/mod.rs)

Testing

Built with --all-features and ran 3d_scene example.

the changes are straightforward and compile on my machine - the CI changes are above my pay grade - any idea what's happening?

This is pretty straightforward: looks like a missed import swap. The code is probably cfg-gated; hence why it's not showing up locally. Try a search within the bevy_render directory for tracing of "use tracing" to spot more that you missed :)

LGTM

I've been mildly annoyed by this for a while so I'm glad it's finally getting fixed!

i updated to latest rust (1.93.0) to match CI and when i do cargo fit --all locally it also gets an error from rustfmt - worked on prior version (1.92.0) but not now

We should probably file a bug upstream for this with a reproduction.
