2d project without `default-features` fails to compile without `bevy_pbr` feature on wasm targets

[rparrett]

Bevy version

main, bisected to #10057

Relevant system information

AdapterInfo { name: "Apple M1 Max", vendor: 0, device: 0, device_type: IntegratedGpu, driver: "", driver_info: "", backend: Metal }
SystemInfo { os: "MacOS 14.2.1 ", kernel: "23.2.0", cpu: "", core_count: "10", memory: "64.0 GiB" }

What you did

cargo run --example sprite --no-default-features \
--features=bevy_asset,bevy_core_pipeline,bevy_render,bevy_sprite,bevy_text,bevy_ui,bevy_winit,multi-threaded,webgl2,x11,png \
--target=wasm32-unknown-unknown

(adding bevy_pbr to that list causes compilation to succeed)

Workaround

Users can work around this by adding the following to their Cargo.toml

[target.'cfg(target_arch = "wasm32")'.dependencies]
# Workaround for Bevy #11908
naga_oil = "*"
