For some specific cases (one of them see below) where are requirement to
identify the reason of the attribute mutation (by whom/why it was
changed - by cloning, parser or directly), so the following `reason`
parameter was added to `AttributeMutation::Set` option.
Note that for the HTMLMediaElement the internal `muted` state should be
set to true when the element is created and the element has a `muted`
content attribute specified (should be done once on the first attribute
mutation caused by parser or cloning).
See https://html.spec.whatwg.org/multipage/#dom-media-muted
Testing: Improvements in the following tests

Servo has a lot of comments like this:
```rust
// https://example-spec.com/#do-the-thing
fn do_the_thing() {}
```
and I keep turning these into doc comments whenever I'm working close to
one of them. Doing so allows me to hover over a function call in an IDE
and open its specification without having to jump to the function
definition first. This change fixes all of these comments at once.
This was done using `find components -name '*.rs' -exec perl -i -0777
-pe 's|^([ \t]*)// (https?://.*)\n\1(fn )|\1/// <$2>\n\1$3|mg' {} +`.
Note that these comments should be doc comments even within trait `impl`
blocks, because rustdoc will use them as fallback documentation when the
method definition on the trait does not have documentation.
Testing: Comments only, no testing required
