We are currently porting Chromium over to use the Perfetto client
library for tracing[1]. When this mode is enabled, V8 should also use
the Perfetto library built by Chromium instead of building an
indepedendent copy. This patch enables that behavior, gated by the
|use_perfetto_client_library| flag set by Chromium.
We also roll Perfetto to the latest version, add a couple of missing
dependencies on v8_tracing and add a missing tracing category group.

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.
