test: enable linting for tests Enable linting for the test directory. A number of changes was made so all tests conform the current rules used by lib and src directories. The only exception for tests is that unreachable (dead) code is allowed. test-fs-non-number-arguments-throw had to be excluded from the changes because of a weird issue on Windows CI.

test: remove unused assert module imports Many test modules load assert but do not use it. This change removes those instances. It also removes a handful of other unused variables when they were nearby.

vm: update API to use options argument Passing a filename is still supported in place of certain options arguments, for backward-compatibility, but timeout and display-errors are not translated since those were undocumented. Also managed to eliminate an extra stack trace line by not calling through the `createScript` export. Added a few message tests to show how `displayErrors` works. 12 years ago			`var vm = require('vm');`

src: attach error to stack on displayErrors The vm module's displayErrors option attaches error arrow messages as a hidden property. Later, core JavaScript code can optionally decorate the error stack with the arrow message. However, when user code catches an error, it has no way to access the arrow message. This commit changes the behavior of displayErrors to mean "decorate the error stack if an error occurs."
