Exclude swift-testing macro (@Test) in identifier_name rules

[coffmark]

Describe your changes

• Exclude swift-testing macro (@Test) in identifier_name rules.
• User can set excluded_swift_testing configuration as you needed.

Motivation

Normally functions should be implemented starting with a lowercase letter, but when using swift-testing, there're cases where you want to write test cases in the function name that aren't lowercase.

The following example is a Japanese implementation of a function named "This is a test".

This PR, using the excluded_swift_testing flag, allows user to prevent errors (or warnings) from occurring in functions with @Test macros implemented.

// before
@Test func これはテストです() { } // swiftlint error (`identifier_name`)  

// after (when `excluded_swift_testing` is true)
@Test func これはテストです() { } // no error

// after (when `excluded_swift_testing` is false)
@Test func これはテストです() { } // swiftlint error (`identifier_name`)
