Improve attribute handling in opaqueGenericParameters rule

[calda]

This PR improves attribute handling in the opaqueGenericParameters rule.

To fix #1684, https://github.com/nicklockwood/SwiftFormat/commit/383fd4813c7fb45e4e996242b6c7c919133f5dc1 made it so the opaqueGenericParameters was disabled for all functions with attributes. However, in most cases attributes don't cause any issues. For example:

@MyResultBuilder
func foo<T: Foo, U: Bar>(foo: T, bar: U) -> MyResult {
    foo
    bar
}

@MyFunctionBodyMacro(withArgument: true)
func foo<T: Foo, U: Bar>(foo: T, bar: U) {
    print(foo, bar)
}

This PR tweaks the existing fix to check the tokens of the attributes, and whether or not they reference any of the generic arguments. #1684 remains fixed, and the above examples are now updated as expected:

@MyResultBuilder
func foo(foo: some Foo, bar: some Bar) -> MyResult {
    foo
    bar
}

@MyFunctionBodyMacro(withArgument: true)
func foo(foo: some Foo, bar: some Bar) {
    print(foo, bar)
}
