Land v8-side changes to switch to v8_current_cpu in the GN build.

Browse Source 
This change makes  the architecture that we target generated
v8 code for a property of the current toolchain, rather than a
global setting that applies to every toolchain.

This will allow us to properly build two snapshots for two different
architectures in a single build, which is needed for android
webview/monochrome builds.
