Subject: [PATCH] set pipeline to queued when shader is not yet available
 (#12051)

# Objective

- Fixes #11977 - user defined shaders don't work in wasm
- After investigation, it won't work if the shader is not yet available
when compiling the pipeline on all platforms, for example if you load
many assets

## Solution

- Set the pipeline state to queued when it errs waiting for the shader
so that it's retried
