Volumes and VolumesMounts can be used to mount wasm files. Does it need to add additional fields?

I think it doesn't need additional fields, just specify the hostPath of the wasm file.
Like this:
wasmFile:
hostPath:
path: /etc/wasm/

Does this mean the WasmPath must begin with /fluent-bit/wasm?

Yes. Because I noticed that's what PositionDB does. Maybe more comments should be added or is there a better way?

I recommend using Volumes and VolumesMounts to mount wasm files, so you can specify any directory.

Does this PR introduced a user-facing change?
The wasm file needs to be mounted to the fluent bit. I tried writing the wasm file to secret or configmap, but it was too long, and I ended up mimicking the way Position DB was mounted.
