This patch re-lands #36193 with a couple of minor tweaks
including updating the BUILD.gn file to use the new
variable name and incorporating thakis' request to support
cross-compiling the win snapshot from a mac.

It is likely that CrOS and other distros will want to be
able to build the v8 snapshot with a custom toolchain.
This CL makes snapshot_toolchain a declared build arg, and
renames it to v8_snapshot_toolchain to minimize the risk
of a name collision.

We need to build parts of v8 with a toolchain that might be different
from both the default (target) toolchain and the regular host toolchain,
because we need the snapshot to have the same bit-width as the target.
V8's build defines a 'snapshot_toolchain' setting for this.
It turns out that we need the value of this toolchain to be exposed
to the Chromium build because some of the test targets (in browser_tests)
depend on d8 and need to be able to built using the same toolchain.
