James Liu 79b9231b74 Move system_commands spans into apply_buffers (#6900) ... # Objective A separate `tracing` span for running a system's commands is created, even if the system doesn't have commands. This is adding extra measuring overhead (see #4892) where it's not needed. ## Solution Move the span into `ParallelCommandState` and `CommandQueue`'s `SystemParamState::apply`. To get the right metadata for the span, a additional `&SystemMeta` parameter was added to `SystemParamState::apply`. --- ## Changelog Added: `SystemMeta::name` Changed: Systems without `Commands` and `ParallelCommands` will no longer show a "system_commands" span when profiling. Changed: `SystemParamState::apply` now takes a `&SystemMeta` parameter in addition to the provided `&mut World`.		2022-12-11 23:04:04 +00:00
