comments and reformat with a Vim macro and gn format.

Sets up clang and gcc based toolchains for all host target builds.
Defaults to using Clang for linux/mac and GCC for windows.

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

This CL reworks toolchains to be defined as scopes composing configs and
toolchain args. This allows individual targets to add configs to or
remove configs from the defaults.

Adds a linker flag to the generated cortex-m4 and cortex-m3 toolchains
to enable printf formatting of floating point numbers.

Introduces the lm3s6965evb target designed to run inside QEMU. Not all
tests have been verified on this target, but the target builds and
successfully runs some of the tests.

* Add Cortex-M4 toolchains with floating point hardware instructions.
* Update stm32f429i-disc1 to use hardware fpu toolchain by default.
* Add code to enable FPU in pw_dumb_io.
Verified tests that use floating point operations continue to pass.

- Update host_clang to work on Linux: switch to -Map and --gc-sections
options
- Make pw_target_toolchain a build arg for Linux and macOS targets.
Default to gcc on Linux, clang on macOS.
- Rename x86_linux_gcc to host_gcc.

This adds a generic host_clang toolchain, targeting hosts running Mac and
Linux to start, and likely Windows later.
For now, on Mac the default toolchain is set to host_clang_og

- Add -fdiagnostics-color so that compiler warnings are colorized. The
way Ninja invokes GCC disables colors by default.
- Move -Wno-psabi up to the arm_gcc_toolchain template so that it
doesn't have to be specified for each arm_gcc_toolchain instance.
- Add -Werror to the strict_warnings config to prevent warnings from
slipping through. Exempt a few warnings that should actually be
warnings.

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.
