Detect redundant Default implementations #7550
Description
What it does
Detects custom std::default::Default implementations that are identical to a derived implementation. This could probably be done with other derive attributes, but I think Default is a fairly common one that people may implement themselves.

What is the advantage of the recommended code over the original code
It is more concise.
Drawbacks
I have no clue about the internals of Clippy, so I'm not sure how hard it would be to implement.
Example
struct Foo {
bar: bool
}
impl std::default::Default for Foo {
fn default() -> Self {
Self {
bar: false
}
}
}Could be written as:
#[derive(Default)]
struct Foo {
bar: bool
}
