Bug 1825014 part 4 - Use a rest parameter instead of arguments for some error-throwing functions. r=iain

This eliminates the remaining uses of `arguments` in self-hosted code.

These functions are called from C++ code. I'll see if we can remove them in a follow-up bug.

These can be used to replace uses of `arguments.length` and `arguments[i]` in
self-hosted code.

The frontend emits specialized bytecode ops for those instructions that access
the frame directly. This means we no longer have to allocate an arguments object in
the interpreter and Baseline for self-hosted functions. This speeds up many
perf-sensitive builtins such as `ArrayMap`.

Later patches convert all `arguments` uses in self-hosted code and add assertions to
ensure we never create an arguments object for any self-hosted function.

Before this commit, the New Tab tests had two fake pref
implementations:

* The `Services.prefs` mock in `TEST_GLOBAL`, which stubbed out a
  handful of `nsIPrefBranch` methods.
* `FakensIPrefBranch`, which mocked a different handful of
  `nsIPrefBranch` methods.

This commit:

* Consolidates the two fake implementations into the mock
  `FakensIPrefBranch` class.
* Adds a `FakensIPrefService` subclass of `FakensIPrefBranch`, with
  additional methods specific to `nsIPrefService`.
* Replaces `FakensIPrefBranch.prototype.prefs` with a new
  `FAKE_GLOBAL_PREFS` map. The new approach still lets tests change and
  clear prefs on existing instances of `FakensIPrefBranch` and its
  subclasses, but makes the shared state explicit. The old approach of
  mutating `FakensIPrefBranch.prototype.prefs` relied on a subtle quirk
  of `prefs` being shared by all instances of `FakensIPrefBranch` and
  its subclasses, and broke when setting `prefs` to a new, empty
  object.
* Moves `{observe, ignore}Branch` into `FakePrefs`, since these are
  not part of the `nsIPrefBranch` interface.

mScale is the zoom at the time the displayport margins were set, but
the resulting ScreenMargin will be interpreted in the context of the
scale at which we're about to paint, which may be different.

Note that mMargins themselves are not affected by these two scales
being potentially different, since we want the magnitude of the
margins to the constant in Screen pixels (i.e. a constant fraction
of the viewport size).

This revision adds logic to BoundsWithOffset to ensure that bounds, when
calculated for hit testing, are constrained to the scroll areas that contain
them. This ensures that we don't return an Accessible that's covered by another
element when hit testing due to overflow: scroll situations.

This revision also contains a fix for transforms and scroll: we now apply
scroll before any transform, since transforms operate on scrolled content.

This revision contains tests for both of the above changes.
