Remove the need to derive Event when deriving EntityEvent (#20104)
# Objective
Since we are planning to remove the need to derive both `Event` and
`EntityEvent` in 0.17 either way, I'm choosing to do the easy thing in
this PR so we can get the churn out of the way early.

Related to, and will conflict slightly with #20101.

## Solution

- Derive `Event` as part of the `EntityEvent` derive
- Remove any `Event` derives that were made unnecessary
- Update release notes

Bevy Benchmarks

This is a crate with a collection of benchmarks for Bevy.

Running benchmarks

Benchmarks can be run through Cargo:

# Run all benchmarks. (This will take a while!)
cargo bench -p benches

# Just compile the benchmarks, do not run them.
cargo bench -p benches --no-run

# Run the benchmarks for a specific crate. (See `Cargo.toml` for a complete list of crates
# tracked.)
cargo bench -p benches --bench ecs

# Filter which benchmarks are run based on the name. This will only run benchmarks whose name
# contains "name_fragment".
cargo bench -p benches -- name_fragment

# List all available benchmarks.
cargo bench -p benches -- --list

# Save a baseline to be compared against later.
cargo bench -p benches -- --save-baseline before

# Compare the current benchmarks against a baseline to find performance gains and regressions.
cargo bench -p benches -- --baseline before

Criterion

Bevy's benchmarks use Criterion. If you want to learn more about using Criterion for comparing performance against a baseline or generating detailed reports, you can read the Criterion.rs documentation.
