tldr: This adds an on-demand comparison with x64 when a difference to
a non-x64 build is detected.
Normally foozzie compares the baseline build (just ignition), with
two secondary builds. One, the default, always uses the shipping
configuration, the second passes additional flags. Both can use a
different architecture than the baseline build as well.
Differences between ignition and turbofan are then often detected
independent of the architectures used, but reported several times
(for each compared architecture).
This makes the reporting more specific, by running another build on
demand that uses the baseline architecture, but otherwise the same
configuration that showed a difference. If it shows the difference as
well, the baseline architecture is used for the report.
As a result only pure architecture differences will be reported with
an architecture other than x64.
This also adds some minor refactorings to reduce the code complexity
when looping over comparisons.
For testing this, the fake-d8s are extended with different behavior
for different flags passed. We add two test cases for testing:
x64 vs. ia32 with difference in x64 and ia32
x64 vs. ia32 with difference only in ia32

Most NativeContext elements are immutable after initialization;
additionally, we now use acquire-release semantics to load/store
elements when possible. Reading and constructing Refs for elements
is thus possible from the background.
A few notes:
- A few elements are not immutable; if read from the background
thread, these must use acquire-release semantics.
- Elements can be stored from generated code; these are not compatible
with bg-thread accesses.
- While elements can be read safely from the native context, the
elements themselves may still require serialization; this is done in
NativeContextRef::Serialize.

The method changes a global flag, depending upon which v8 attaches or
not the SharedArrayBuffer constructor to global objects. Chrome ended
up calling it when some contexts had already been created, leading to
inconsistencies. (Also) because of that, we decided to change the
mechanism for enabling cross-origin isolation (cf.
https://crrev.com/c/2880215). I believe it is better not to expose
this method.

change was outside of the scope of the MapUpdater. In order to have a
consistent view of the data, the concurrent reader will access the map
updater lock if needed.
Also refactor MapUpdaterMutexDepthScope (now named
`MapUpdaterGuardIfNeeded`) so that A) it's not possible to forget to
lock it, and B) add V8_NODISCARD to the class.
As a second refactor use std::function in TraverseCallback.
