Previously building `//:noicu/mksnapshot` on M1 macs produced this
linker error:
```

ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
```
Because this branch that enabled the trap handler:
```
// Arm64 (non-simulator) on Mac.
#elif V8_TARGET_ARCH_ARM64 && V8_HOST_ARCH_ARM64 && V8_OS_DARWIN
```
Wasn't handled in the build, so the file was excluded.

Clang 12 doesn't support -Wno-bitwise-instead-of-logical,
so silence it with -Wno-unknown-warning-option.
GCC requires using GNU dialect of the C++ standard, using
optimizations (otherwise "always_inline" fails to inline),
and produces a lot of warnings that had to be silenced.

There is no reason for bazel/config to be used as an external dependency
(we can replace "@v8//bazel/config" as easily as "@config") and it makes
integration with other Bazel workspaces much harded than it needs to be.

This CL renames a number of things related to the V8 sandbox.
Mainly, what used to be under V8_HEAP_SANDBOX is now under
V8_SANDBOXED_EXTERNAL_POINTERS, while the previous V8 VirtualMemoryCage
is now simply the V8 Sandbox:
V8_VIRTUAL_MEMORY_CAGE => V8_SANDBOX
V8_HEAP_SANDBOX => V8_SANDBOXED_EXTERNAL_POINTERS
V8_CAGED_POINTERS => V8_SANDBOXED_POINTERS
V8VirtualMemoryCage => Sandbox
CagedPointer => SandboxedPointer
fake cage => partially reserved sandbox
src/security => src/sandbox
This naming scheme should simplify things: the sandbox is now the large
region of virtual address space inside which V8 mainly operates and
which should be considered untrusted. Mechanisms like sandboxed pointers
are then used to attempt to prevent escapes from the sandbox (i.e.
corruption of memory outside of it). Furthermore, the new naming scheme
avoids the confusion with the various other "cages" in V8, in
particular, the VirtualMemoryCage class, by dropping that name entirely.
Future sandbox features are developed under their own V8_SANDBOX_X flag,
and will, once final, be merged into V8_SANDBOX. Current future features
are sandboxed external pointers (using the external pointer table), and
sandboxed pointers (pointers guaranteed to point into the sandbox, e.g.
because they are encoded as offsets). This CL then also introduces a new
build flag, v8_enable_sandbox_future, which enables all future features.
