The snapping during scene building is unable to take into account scroll
offsets. Since we have already snapped the primitive rects in the raster
space, we know that this can only result in a translation rather than a
size change, and thus is safe to do during frame building.

When we update the transform tree, we now snap the scroll offset in
device space to ensure that scroll offsets should primarily be integer
offsets and not have snapping implications.

The local rect of a picture is calculated during the first picture
traversel. It is composed of already snapped primitives, however the
picture itself may inflate itself, and thus is now snapped again as part
of inflation.

Now that rounding has been removed from Gecko, we need to start snapping
properly in WebRender. Snapping can change the size of a primitive, and
thus it is problematic to do any later than scene building due to the
GPU caching and sharing of data between clips and such that only differ
in their positioning.

This patch produces a snapping transform which allows any primitive to
snap using information known during scene building. This excludes
animated tranforms which are assumed to be the identity. This allows for
primitives that are marked as will-change: transform but given no
initial transform to render the same as primitives that are not. This
also excludes scroll positioning because that is not known until frame
building. A follow up patch will deal with that.

Rounding in layout pixels is very close to snapping in raster pixels if
there are no transforms involved. This is why it worked most of the time
and fell flat in many edge cases. In future parts of this series, we
will trust scene building and frame building to do the heavy lifting for
snapping purposes.

This will be rewritten in a later patch in the series. The shaders will
be provided the correct information and will no longer need to concern
themselves with snapping.

Repeating/background images may have extra parameters such the stretch
size and tile spacing, that non-repeating images do not require. By
splitting these apart, we can make it easier to infer what we should do
if snapping changes the size of an image primitive, in addition to
reducing the display list size for non-repeating images.

`register` isn't allowed in C++17, but cairo is too old to care.
Instead of turning off the warning, just use the `__builtin_popcount`
path for clang.  This path also applies to clang-cl.

This commit uses gc::SystemAddressBits() to disable huge memory in low address
space situations on process startup. I've tried to pick a conservative number
here, but it may require some tuning.

Some systems can limit the available virtual memory (e.g. ulimit -v) and this
takes effect independently of gc::SystemAddressBits(). This commit uses
'getrlimit' to detect any limit, and if set uses this as another heuristic to
disable huge memory.

Additionally, this change requires a change to the initialization order of JS
systems (Wasm <-> GC).

This patch changes a few things about how nsFrameLoader is created, specifically
around the ChangeRemoteness API.

1. The private 'nsFrameLoader::nsFrameLoader' constructor has been simplified to
   only have one overload, shared by the different `::Create` static methods.

2. The creation static method used by `ChangeRemoteness` has changed name to
   `::Recreate`, as the signature is becoming more like the old method.

3. The `mNetworkCreated` bit is preserved when doing a `ChangeRemoteness`, as a
   remoteness change shouldn't be affecting that property.

4. Unused fields are removed from the ChangeRemoteness API.

5. The `remoteType` attribute is now mandatory in the ChangeRemoteness API,
   which simplifies the logic and makes it harder to accidentally misuse.

The (non-normative) window.open spec does not specify what should happen when
window.open is called on a window with a null/discarded browsing context, but
in general the lookup and creation rules do not make sense when the window has
no BC. It does, however, specify that we should return null when a target BC
cannot be found or created, and gives us broad discretion over when we decide
to ignore a load request and return null. Since we can't trigger a
cross-process load from a discarded BC, simply aborting in that case seems
like the logical solution.

For Location objects, the spec is more specific, and requires that we ignore
load attempts on Location objects whose documents are null, which in our
implementation corresponds to a discarded BrowsingContext.
LocationBase::SetURI already enforces this, but a second check in
BrowsingContext::LoadURI is probably a good idea as well.
