Merge #398

398: Add the cfgs on a task to the module for that task r=korken89 a=AfoHT

Applying a `#[cfg(never)]` on a task:

before:

```
#[allow(non_snake_case)]
#[doc = "Software task"]
pub mod foo2 {
    #[doc(inline)]
    pub use super::foo2Resources as Resources;
    #[doc = r" Execution context"]
    pub struct Context<'a> {
        #[doc = r" Resources this task has access to"]
        pub resources: Resources<'a>,
    }
    impl<'a> Context<'a> {
        #[inline(always)]
        pub unsafe fn new(priority: &'a rtic::export::Priority) -> Self {
            Context {
                resources: Resources::new(priority),
            }
        }
    }
      <...>
```

After:

```
#[allow(non_snake_case)]
#[cfg(never)]
#[doc = "Software task"]
pub mod foo2 {
    #[doc(inline)]
    pub use super::foo2Resources as Resources;
    #[doc = r" Execution context"]
    pub struct Context<'a> {
        #[doc = r" Resources this task has access to"]
        pub resources: Resources<'a>,
    }
    impl<'a> Context<'a> {
        #[inline(always)]
        pub unsafe fn new(priority: &'a rtic::export::Priority) -> Self {
            Context {
                resources: Resources::new(priority),
            }
        }
    }
    <...>
```
