[roll third_party/pigweed] pw_build: Configurable Python and proto toolchains

- Rename pw_toolchain/dummy to pw_toolchain/default to make its intended
  purpose clear. Keep pw_toolchain/dummy around for compatibility.
- Create a template that generates non-C++ toolchains. This is used for
  non-C++ tasks like Python and proto. GN parses build files differently
  in the default toolchain (all targets are instantiated), so the
  these toolchains can be used when that is not desired.
- Make pw_python_package's toolchain configurable with the
  pw_build_PYTHON_TOOLCHAIN arg.
- Make pw_proto_library's toolchain configurable with the
  pw_protobuf_compiler_TOOLCHAIN arg.
