The new `tint-generate-coverage` CMake target can be used with the clang toolchain to generate a `lcov.info` file at the root of the project, along with a `coverage.summary` human readable plain text file.
The `lcov.info` file can then be used by various tools to display code coverage information in your IDE / code editor.
Useful for ensuring decent test coverage.
