Warning `Too many textures in mesh pipeline view layout` when using SSAO and TAA together

## Bevy version

0.18.0

## Relevant system information

- rustc 1.93.0 (254b59607 2026-01-19)
- Windows 11

```ignore
SystemInfo { os: "Windows 11 Pro", kernel: "26200", cpu: "AMD Ryzen 5 7500F 6-Core Processor", core_count: "6", memory: "31.6 GiB" }
AdapterInfo { name: "NVIDIA GeForce RTX 4070 SUPER", vendor: 4318, device: 10115, device_type: DiscreteGpu, driver: "NVIDIA", driver_info: "591.74", backend: Vulkan }
```

## What you did

Trying to use the SSAO and the TAA together:

```rust
use bevy::{anti_alias::taa::TemporalAntiAliasing, pbr::ScreenSpaceAmbientOcclusion, prelude::*};

fn setup(mut commands: Commands) {
commands.spawn((
Camera3d::default(),
ScreenSpaceAmbientOcclusion::default(),
TemporalAntiAliasing::default(),
Msaa::Off,
));
}

fn main() {
App::new()
.add_plugins(DefaultPlugins)
.add_systems(Startup, setup)
.run();
}
```

## What went wrong

It prints the warning:

```
2026-01-31T02:59:51.590974Z WARN bevy_pbr::render::mesh_view_bindings: Too many textures in mesh pipeline view layout, this might cause us to hit `wgpu::Limits::max_sampled_textures_per_shader_stage` in some environments.
```

Reproduce the minimal example with ScreenSpaceAmbientOcclusion and TemporalAntiAliasing enabled, then inspect the bevy_pbr::render::mesh_view_bindings warning and the mesh pipeline view layout. Done means the two features work together without the max_sampled_textures_per_shader_stage warning on the reported setup.
