* refactor: preliminary cleanup of Deno.runTests() * Change time measurement to use new Date() instead of performance.now(). Because there is no guarantee that tests are run with "--allow-hr" using new Date() guarantees higher precision of 1ms instead of 2ms. * Support String type filter in "skip" and "only". * Split "exitOnFail" into "exitOnFail" and "failFast". Former tells if "runTests()" should exit with code 1 on test failure, while latter tells if "runTests()" should stop running tests on first failure. * Use "defer" to wait for unhandled promise rejection - this bit is funky and doesn't seem right, but for now it's just a rewrite from using "setTimeout". Intended to be fixed in later commits. * Remove global "__DENO_TEST_REGISTRY", don't expose list of registered tests (to be addressed in follow up commits) * Remove arbitrary slow test threshold; use uniform coloring instead
