`ShaderModule` creation error isn't handled on web

## Bevy version and features

0.19

## What you did

Load an invalid Shader on web

## What went wrong

Application quits due to validation error

## Additional information

See https://github.com/bevyengine/bevy/blob/e8b3598ff5e5ec40e8ba84edd5750a1c0e4d4e59/crates/bevy_render/src/render_resource/pipeline_cache.rs#L162-L170

We should get shader compilation info and validation error and return Err when failing.

However this may be non-trivial because `ShaderModule::get_compilation_info` and `ErrorScopeGuard::pop` are async function which can't be blocking on web.

Start in crates/bevy_render/src/render_resource/pipeline_cache.rs at lines 162-170, where ShaderModule creation errors are currently handled. Investigate the web behavior of ShaderModule::get_compilation_info and ErrorScopeGuard::pop, then verify that an invalid shader reports an error instead of quitting the application.
