Support pattern matching for Style/IdenticalConditionalBranches cop #9855

This PR supports Ruby 2.7's pattern matching syntax for Style/IdenticalConditionalBranches cop.

This Style/IdenticalConditionalBranches cop is detecting for if and case.
Therefore, I think about detecting case-match with the cop instead of a new cop.

It may also be suitable for the cop's role of detecting duplicated conditional branches.


Before submitting the PR make sure the following are checked:

  • The PR relates to only one subject with a clear title and description in grammatically correct, complete sentences.
  • Wrote good commit messages.
  • Commit message starts with [Fix #issue-number] (if the related issue exists).
  • Feature branch is up-to-date with master (if not - rebase it).
  • Squashed related commits together.
  • Added tests.
  • Ran bundle exec rake default. It executes all tests and runs RuboCop on its own code.
  • Added an entry (file) to the changelog folder named {change_type}_{change_description}.md if the new code introduces user-observable changes. See changelog entry format for details.
