TSL: Fix two issues in StorageTextureNode

[PoseidonEnergy]

Issue 1

In StorageTextureNode.generateStore(), this line:

const snippet = builder.generateTextureStore( builder, textureProperty, uvSnippet, depthSnippet, storeSnippet );

should be changed to this:

const snippet = builder.generateTextureStore( this.value, textureProperty, uvSnippet, depthSnippet, storeSnippet );

This is because the first argument to WGSLNodeBuilder.generateTextureStore() is for the texture, not the builder.

Issue 2

Because StorageTextureNode.generateStore() does not return anything/returns void, the method StorageTextureNode.generate() should return '' if this.storeNode !== null.

Therefore, this logic:

generate( builder, output ) {

	let snippet;

	if ( this.storeNode !== null ) {

		snippet = this.generateStore( builder );

	} else {

		snippet = super.generate( builder, output );

	}

	return snippet;

}

should be changed to this:

generate( builder, output ) {

	if ( this.storeNode !== null ) {

		this.generateStore( builder );
		return '';

	}

	return super.generate( builder, output );

}
