Problem: Insufficient test coverage for validation of option values.
Solution: Port Vim's gen_opt_test.vim and make it work with Nvim.
vim-patch:9.1.0760: tests: no error reported, if gen_opt_test.vim fails
vim-patch:9.1.0791: tests: errors in gen_opt_test.vim are not shown
- Consistently use the variable CMAKE_BUILD_TYPE to select build type.
- Remove broken `doc_html` target.
- Remove swap files created by oldtest when cleaning.
- Only rerun `lintdoc` if any documentation files has changed.
Problem: Elapsed time since testing started is not visible.
Solution: Show the elapsed time while running tests.
