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.

Calling v8.setFlagsFromString with e.g a function as a flag argument
gave no exception or warning that the function call will fail.
There is now an exception if the function gets called with the wrong
flag type (string is required) or that a flag is expected.
Other APIs already provide exceptions if the argument has not the
expected type.
