This patch replaces V8's tracing implementation (i.e., the TRACE_EVENT
macros) with the track event base implementation from Perfetto. The
advantages of doing this are:
1) This allows us to remove most tracing-related backend code from V8.
2) V8 can start writing strongly typed trace event arguments, which
are more compact, easier to process and more extensible than legacy
JSON-based trace arguments.
For the time being, we still support the old trace macros when V8 is
embedded into Chrome and other embedders.

This adds dependencies on Perfetto and Protobuf and the required
configs to build them.
The build configs are behind a gn flag (v8_use_perfetto) and
are disabled by default. Actual implementation of Perfetto will follow.
Based on Primiano's prototype:

Because of the android sdk managed by CIPD (see go/use-adjective-apis),
its deps repo ndk needs to be relocated to third_party/android_ndk.
This CL changes the ndk root path in files in v8.

v8 now uses the same SDK as Chromium, even when built as a standalone project.
The deployment target override has no effect.

Chrome now uses the default_args system for specifying its own definitions of
these variables so the separate file in build_overrides is no longer necessary.

We're converting the build_overrides system to the new default_args list of
overrides that can be listed in the toplevel .gn file. This will allow args to
be set on a per-repo basis.
This change conditionally adds the variables currently defined in
build_overrides/v8.gni to build args. This allows V8's build to be used in both
the new and old systems. Once all Chrome and pdfium have been updated, v8's
build overrides and the conditional checks around the new args can be removed.

Instead of directly using v8_enable_inspector_override from
build_overrides/v8.gni in all the GN configs, set a v8_enable_inspector
variable based on v8_enable_inspector_override and use that everywhere.
This is the more common pattern seen in over projects, and reduces the
need to include //build_overrides/v8.gni in many files.

To achieve this:
- fixed crash on windows - String16::fromInteger used "%zu" which doesn't support by VS2013 compiler, wrapped with ifdef else.
- fixed asan for d8 - unique_ptr on array has single element type.
- force Debugger.disable at the end of test.

- inspector becomes a dependency of v8_base;
- generated public protocol files are placed to gen/v8/include/inspector/<Domain.h>;
- added v8_enable_inspector_override to be used in embedders (gn only);
- combined public headers into v8-inspector.h and v8-inspector-protocol.h.

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.

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.
