Recommend/Autofix - Use Nested Resource Declaration

A static analysis issue should detect when a nested resource declaration could be used and provide an autofix for this.

I should also be able to fix the entire file at once if there are multiple resources linked as parents.

If there are certain edge cases where this is not the recommend approach those should be detected and allowed.

Use nested resource declaration with existing to reduce the nested templates.

Start by locating the static-analysis rule for nested resource declarations and the existing autofix infrastructure. Define which parent-linked resources can use nested declarations, support fixing all eligible resources in a file, and verify that documented edge cases remain unchanged.
