compositing: Split Servo up into multiple sandboxed processes.
Multiprocess mode is enabled with the `-M` switch, and sandboxing is
enabled with the `-S` switch.
Rebase of #6884.

Remove unnecessary uses of #[no_move]
The patch makes RootCollection a bit safer by making the StackRootTLS hold
it in place.
RootedVec was doing an extremely delicate dance and just hoping nobody
messed it up; switch to a Box to be safe.
CodeGenRust seemed to be using no_move for no particularly good reason.

The patch makes RootCollection a bit safer by making the StackRootTLS hold
it in place.
The use of no_move in CodeGenRust was leftover from when roots couldn't
be moved.
This should make it somewhat easier to experiment with alternative
representations in the future. To reduce churn, this commit leaves the String
field public, though.
Also, this will allow us to use the default String type to represent the IDL
USVString type, which explicitly forbids unpaired surrogates, ans as such is
a better match to the Rust String type.
Introduce VirtualMethods::children_changed()
This virtual method mimics the behaviour of mutation observers and make it more viable than the older child_inserted(), which didn't cover removed nodes and was called as many times as there were inserted nodes.
A few other shortcomings where remove_child() was called directly instead of Node::remove() were also fixed while at it.

To actually make the multiprocess communication work, we'll need to
reroute the task creation to the pipeline or the compositor. But this
works as a first step.
Fix a few issues
- Use SmallVec<[T; N]>
- Make find_iframe a free function
- Make ProgressEvent use enums for bubbles and cancelable
- Change README, as `rust-snapshot-hash` is just a text file
