Add GetShaderPrecisionFormat argument validation
This patch adds a check on the shader_type argument. If it is not one either
FRAGMENT_SHADER or VERTEX_SHADER, we return INVALID_ENUM.

Fix PromiseRejectionEvent constructor when promise argument is None
Due to lack of `required` of the `promise` argument in webidl, we need to handle this so that it can be correct behavior. And then the constructor test will be passed!

Unify the task source and task canceller API
To do so, I created a struct `TaskManagement(TaskSource,
TaskCanceller)` and made `*_task_source` return that instead of just
the task source.
Next, I refactored all places in which `task_canceller` by basically
removing them in favour of a previously called `*_task_source`.
I tried to make `task_canceller` a private method in `Window`, with the
hope of enforcing the use of `*_task_source`. However, it's used in
components/script/dom/globalscope.rs:575 in such a way that will make it
harder to avoid. I decided to leave it that way.
It'd be possible to unify `*_task_source` in such a way that we would
have only one method. However, I decided not to do it because one of the
`TaskSource` implementations is special:
`history_traversal_task_source`. Not wanting to over complicate things,
I decided to leave the structure this way.

I moved away from the `Window` struct all the logic to handle task
sources, into a new struct called `TaskManager`. In a happy world, I'd
be able to just have there two functions, of the types:
```rust
fn task_source<T: TaskSource>(&self, name: TaskSourceName) -> Box<T>
fn task_source_with_canceller<T: TaskSource>(&self, name: TaskSourceName)
-> (Box<T>, TaskSourceCanceller)
```
And not so much duplicated code. However, because TaskSource can't be a
trait object (because it has generic type parameters), that's not
possible. Instead, I decided to reduce duplicated logic through macros.
For reasons[1], I have to pass both the name of the function with
canceller and the name of the function without, as I'm not able to
concatenate them in the macro itself. I could probably use
`concat_idents` to create both types already defined and reduce the
amount of arguments by one, but that macro is nightly only. At the same
time, not being able to declare macros inside `impl` forces me to pass
`self` as an argument.
All this makes this solution more verbose than it would be ideally. It
does reduce duplication, but it doesn't reduce the size of the file.

Use line comments instead of block comments
as block comments contain trailing whitespace
after formatting with rustfmt.
Skip tests for malloc_size_of and script_plugins
with rustfmt as they have many block comments.
