Add pw_bloat module
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

Pigweed is a collection of embedded-focused libraries, which we call "modules". These modules are designed for small-footprint MMU-less microcontrollers like the ST Micro STM32L452 or the Nordic NRF82832. The modules are designed to facilitate easy integration into existing codebases.
Pigweed is in the early stages of development.
