framework: Split framework code

The framework contained concurrency bugs because it was too sprawling
for me to understand. This commit begins splitting the framework code
into two directories, "test" and "runner". Future commits split up
cru_test.c into smaller files and fixes the concurrency the bugs.

- Move framework test code from src/crucible into src/framework/test.
- Move framework runner code from src/crucible into src/framework/runner.
