Drop libprotobuf dependency and update compile_perfetto_protos
to rely on externally provided protoc and protozero_plugin.
This is done because protoc does not build with our current
toolchain and fixing this build requires rolling new protobuf,
protobuf_gn and perfetto. Which also pulls more external dependencies
like abseil.
Regenerate Perfetto *.pbzero{.cc,.h}, *.dart files
TEST=ci

This directory was taken from a snapshot of flutter/engine/src/build/.
The snapshot was taken with a recursive copy cp -R of the directory from
the flutter repository.
The contents has now diverged significantly from Flutter, and is maintained independently by the Dart team. It is used to support the GN build system.
