Remove test of static Context
Context is no longer Sync so this doesn't work.

    error[E0277]: `*mut ()` cannot be shared between threads safely
      --> library/core/tests/task.rs:24:21
       |
    24 |     static CONTEXT: Context<'static> = Context::from_waker(&WAKER);
       |                     ^^^^^^^^^^^^^^^^ `*mut ()` cannot be shared between threads safely
       |
       = help: within `Context<'static>`, the trait `Sync` is not implemented for `*mut ()`
       = note: required because it appears within the type `PhantomData<*mut ()>`
       = note: required because it appears within the type `Context<'static>`
       = note: shared static variables must have a type that implements `Sync`
