What is the purpose of this pull request? (put an "X" next to item)

[X] Changes an existing rule #12808

What changes did you make? (Give an overview)

no-dupe-class-members was ignoring all computed keys.

After this PR, this rule will also check those class members for which astUtils.getStaticPropertyName returns a string value. This is new default behavior.

/*eslint no-dupe-class-members: ["error"]*/

class A {

  ["a"](){} // error

  b(){} // error

  [`c`](){} // error
  123(){} // error


The rule will still ignore computed keys with values that are not statically known:

/*eslint no-dupe-class-members: ["error"]*/

class A {

  [a](){} // no error


Is there anything you'd like reviewers to focus on?
