spirv_shader_passthrough must enable wgpu/spirv (#15873)

# Objective

Fixes #15515

## Solution

I went for the simplest solution because "format" in
`shader_format_spirv` didn't sound directly related.

## Testing

The command `cargo b -p bevy --no-default-features -F
spirv_shader_passthrough,x11` failed before, but works now.
