The isolate_driver automatically adds referenced shared
libraries. They don't need to be listed explicitly.

The hard-coded location blocks the GN transition
as the library location is different in GYP and GN.

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.

The GN configs for different optimization levels are confusing and
should probably be reworked, but for now we add a special config
specifically so that we can compile with -O3 when appropriate.

Using the data file is the default now and it shouldn't
be overridden in v8's build_overrides. Also the isolate
logic now needs to include the gni file specifying the
flag.

This makes the isolate-driver script rebase all paths to be
relative to the isolate-file location. This is an assumption
of the go binaries and is needed for batcharchive to work.

In gyp, actions were executed relative to the gyp file that
specified them, while in gn it's relative to the product dir.

There are bots on the chromium.lkgr waterfall that need to
be able to set v8_target_arch to "arm" while the rest of
the target build is "x86". This CL makes that argument
a declare_arg(), so that we can do that.
