This change adds a module which builds documentation using Sphinx.
Documentation files and assets are defined using a pw_doc_group GN
template which lists out all of the sources as metadata. Another GN
template, pw_doc_gen, collects the metadata from pw_doc_group targets
into a JSON file and defines an action that runs a script to build the
HTML docs.
A docgen script is provided by the pw_docgen module. This script reads
the JSON metadata file collected by a pw_doc_gen template, copies all of
the source and resource files into a documentation tree, and runs Sphinx
on the tree to render the docs as HTML.

This change adds two Pigweed modules: pw_preprocessor and pw_unit_test.
The preprocessor module contains header files providing helpful macros
for the C preprocessor. The unit test module contains a starter
implementation of a unit testing framework for Pigweed.

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.
