Alexei Frolov 925fb8f510 Build and run unit tests through GN
This change adds a GN template for defining unit test executables.
The template, called pw_test, defines the executable and outputs a JSON
metadata file for the test.

A new build argument is added. This argument determines whether unit
test run targets are supported by the current build target. If this is
set, the pw_test template additionally creates a run target for its test
executable which invokes the executable through a script.

A basic test runner script is added to the pw_unit_test module. This
script currently only runs a single test executable directly.

The unit tests in the pw_preprocessor module are updated to use the
pw_test template.
