Define pw_test_group template

This change adds a GN template to the pw_unit_test module which defines
a group of unit tests. The template creates a generated_file target with
JSON metadata for the unit tests and dependencies within the test group.
These metadata files are intended to be parsed by the test runner script
to run unit tests outside of GN.

A pw_test_group target is added to each of the existing modules which
have unit tests.

Pigweed embedded oriented software libraries

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.
