Remove insert_or_spawn function family (#18148)
# Objective

Based on and closes #18054, this PR builds on #18035 and #18147 to
remove:

- `Commands::insert_or_spawn_batch`
- `Entities::alloc_at_without_replacement`
- `Entities::alloc_at`
- `entity::AllocAtWithoutReplacement`
- `World::insert_or_spawn_batch`
- `World::insert_or_spawn_batch_with_caller`

## Testing

Just removing unused, deprecated code, so no new tests. Note that as of
writing, #18035 is still under testing and review.

## Future Work

Per
[this](https://github.com/bevyengine/bevy/issues/18054#issuecomment-2689088899)
comment on #18054, there may be additional performance improvements
possible to the entity allocator now that `alloc_at` no longer is
supported. At a glance, I don't see anything obvious to improve, but it
may be worth further investigation in the future.

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.
