In preparation for applying the more strict indentation linting

tools/eslint-rules/required-modules.js.
This is the only file with indentation that does not conform to the
stricter checks.

The `no-useless-regex-char-class-escape` custom lint rule was introduced
as a less aggressive alternative to some enhancements that were
introduced into ESLint. Those enhancements were blocking us from
updating ESLint. However, they have since been relaxed and the custom
rule is no longer needed. Remove it.

The second argument to "assert.throws" is usually a validation RegExp or
function for the thrown error. However, the function also accepts a
string and in this case it is interpreted as a message for the
AssertionError and not used for validation. It is common for people to
forget this and pass a validation string by mistake.
This new rule checks that we never pass a string literal as a second argument
to "assert.throws". Additionally, there is an option to enforce the
function to be called with at least two arguments. It is currently off
because we have many tests that do not comply with this rule.

A few nits in recent PR comments suggest that we can have slightly more
strict linting for argument alignment in multiline function calls. This
enables the existing linting requirements to apply when one or more of
the arguments themselves are function calls. Previously, that situation
had been excluded from linting.
