This updates pw_protobuf_compiler to always create a target for each
supported protobuf generator, instead of having a build arg to select
which ones to use, simplifying the use of pw_proto_library.

This updates generated protobuf targets to use the format
<target>.<generator> instead of <target>_<generator> to improve
readability.

The "# gn-format disable" comments are no longer necessary. Delete these
comments and reformat with a Vim macro and gn format.

This change configures the Linux clang -Og target as a toolchain with
args. To support this, all Pigweed variables from pw_vars_default are
made into build args, defined within their respective modules.
The Linux clang target/toolchain is the only one that currently works.
Pigweed's other targets will be ported in later changes.

Require targets to explicitly import pigweed variable definitions. This
moves out some necessary logic from the BUILDCONFIG.gn file.

This change adds support for compiling nanopb protobufs using
pw_protobuf_compiler.
The pw_protobuf_langs build variable is renamed to
pw_protobuf_generators as there is no longer a 1:1 mapping of languages.
To compile nanopb, add the "nanopb" generator to pw_protobuf_generators.
The build variable $dir_third_party_nanopb must be set to point to a
local installation of nanopb with GN support:
https://github.com/frolv/nanopb/tree/gn-build
The host build will run a test which compiles nanopb code if
$dir_third_party_nanopb is set.

This change adds a module responsible for invoking the protobuf compiler
to generate code from .proto definition files. It provides a GN template
which performs the codegen operation on a list of input .proto files.
The template currently only supports C++.
