Add redundant typed throws rule

[miguel-jimenez-0529]

This PR adds a new redundantTypedThrows rule, which removes a typed throws (introduced in Swift 6.0) if it is redundant.

For example:

- func foo() throws(Never) -> Int {
+ func foo() -> Int {
      return 0
  }

- func foo() throws(any Error) -> Int {
+ func foo() throws -> Int {
      throw MyError.foo
  }

We don't remove (Error) because we can't guarantee it will reference the Swift.Error protocol (it's relatively common to define a custom error like enum Error: Swift.Error { ... }).
