The multi-snapshot feature is only used on bots, where we need the
ability to execute tests with/without mitigations controllable through a
runtime flag.
This disables the flag by default and only enables it on bot configs.
Note: standard single-snapshot builds silently use the available
snapshot regardless of the value of --untrusted-code-mitigations.

To speed up compilation times, jumbo allows files to be compiled
together. This is a well known method ("unity builds") to both
compile faster and create a poor man's "full program optimization".
We are only interested in compile times.
Background:
https://chromium.googlesource.com/chromium/src/+/master/docs/jumbo.md
Note that jumbo builds are not enabled by default. To try this out,
add use_jumbo_build=true to your GN args.

Before this CL, cctest with component build will depend on the static v8
snapshot target and omit to dump the build configuration.
Now we simply write the configuration when building any v8
executable. In pure library builds, we don't need the configuration, as
it's used by the test framework to auto-detect testing options.

This adds optional multi-architecture builds, allowing to compile
x86 and x64 in one build. The correctness fuzzer can be configured to
compare the two executables, e.g. to compare x86 to x64 run the
launcher with: --second-d8=clang_x86/d8 in an x64 build.
Configuring the executable's architecture is now simplified and
inferred from the gn build configuration.
Building for clusterfuzz has now a new canonical target that can be
used by the infrastructure (defaults to d8).
The clusterfuzz release builder is now defined to compile
multi-arch builds, which will have an effect as soon as the
infrastructure refers to the new clusterfuzz target.

We're converting the build_overrides system to the new default_args list of
overrides that can be listed in the toplevel .gn file. This will allow args to
be set on a per-repo basis.
This change conditionally adds the variables currently defined in
build_overrides/v8.gni to build args. This allows V8's build to be used in both
the new and old systems. Once all Chrome and pdfium have been updated, v8's
build overrides and the conditional checks around the new args can be removed.

Instead of directly using v8_enable_inspector_override from
build_overrides/v8.gni in all the GN configs, set a v8_enable_inspector
variable based on v8_enable_inspector_override and use that everywhere.
This is the more common pattern seen in over projects, and reduces the
need to include //build_overrides/v8.gni in many files.
