- Override built-in targets, which gives more flexibility than
set_defaults.
- Provide the default C++ in the toolchain, which can be overridden by
explicitly specifying a config on a target.
- Remove the C++17 default flags from public configs, since it is no
longer needed.

Starting a new project requires copying Pigweed's BUILDCONFIG.gn as the
foundation for a project's own BUILDCONFIG. This change adds
documentation and some minor changes to the structure of the BUILDCONFIG
to simplify it.

This change defines the build target system used by Pigweed, where the
build is configured using per-target globals imported from a target .gni
file. A single build arg specifying the path to the target file replaces
the previous args.
A default build variables file is provided in the Pigweed root. This
file defines and documents all of the build variables used by Pigweed.
A top-level targets directory is added to define the targets used by
Pigweed developers. Currently, only a "host" target is added, which
configures the build for a development system based on the host OS.

This change makes the default toolchain for the build system an
argument so that it can be configured per build target.

This change adds Pigweed's first few (incomplete) modules: pw_build,
pw_status, and pw_toolchain. The main scaffolding for Pigweed's GN-based
build system is also included, with a root BUILDCONFIG and BUILD.gn file
defining a top-level modules build target.
