Allow assert disable (#2168)
* Add +verilator+noassert flag

This allows to disable the assert check per simulation argument.

* Add AssertOn check for assert

Insert the check AssertOn to allow disabling of asserts.
Asserts can be disabled by not using the `--assert` flag or by calling
`AssertOn(false)`, or passing the "+verilator+noassert" runtime flag.
Add tests for this behavior.
Bad tests check that the assert still causes a stop.
Non bad tests check that asserts are properly disabled and cause no stop
of the simulation.

Fixes #2162.

* Correct file location

* Add description for single test execution

Without this description it is not obvious how to run a single test from
the regression test suite.
