James Liu 934f2cfadf Clean up some low level dependencies (#12858) ... # Objective Minimize the number of dependencies low in the tree. ## Solution * Remove the dependency on rustc-hash in bevy_ecs (not used) and bevy_macro_utils (only used in one spot). * Deduplicate the dependency on `sha1_smol` with the existing blake3 dependency already being used for bevy_asset. * Remove the unused `ron` dependency on `bevy_app` * Make the `serde` dependency for `bevy_ecs` optional. It's only used for serializing Entity. * Change the `wgpu` dependency to `wgpu-types`, and make it optional for `bevy_color`. * Remove the unused `thread-local` dependency on `bevy_render`. * Make multiple dependencies for `bevy_tasks` optional and enabled only when running with the `multi-threaded` feature. Preferably they'd be disabled all the time on wasm, but I couldn't find a clean way to do this. --- ## Changelog TODO ## Migration Guide TODO		2024-04-08 19:45:42 +00:00
