This fixes the macOS host build by adding a bloaty config. However, the
bloaty config isn't quite right; followup work will be needed to decide
if it makes sense to have Mach-O bloat reports.

This change introduces the pw_dumb_io module, a module intended for
pigweed testing and bringup. pw_dumb_io includes a facade, and a backend
implementation using stdio (pw_dumb_io_stdio).

This change adds a size reporting module named pw_bloat. The module
uses Bloaty McBloatface to generate size report cards for binaries. It
provides a GN template which defines an action to perform a size diff
on a group of binary targets.
Example output:
simple_bloat

- Move pw_unit_test_create_run_targets to pw_vars_default.gni so that
targets can set it.
- Keep the default false, but set it to true for the host targets.

- 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

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.
