Subject: [PATCH 1/7] Add tags to force-style tests

Adds an optional "tags" entry in the force style test YAML. This is a
comma-separated list of keywords, which are parsed by CMake and added as labels
for CTest.  This allows more fine-grained filtering of tests. Any
newly-generated YAML file automatically adds the "generated" tag.
