the gn flag v8_enable_raw_heap_snapshots is enabled. For regular

In addition to UBSan, also ASAN needs optimizations.
So this CL doesn't disable optimizations for all sanitizer builds.

jumbo.gni will check whether use_jumbo_build is set or not and
if it's not set it will just check that |jumbo_excluded_sources|
lists do not include non-existing files. That means that there
is little/nothing to lose by always routing v8_source_set that
way, and it adds a bit in build file simplicity and local
checking of |jumbo_excluded_sources|.

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.

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.
