Denis Isaev 7705f82591 Update megacheck to the latest version
Also do following improvements:
  - show proper sublinter name for megacheck sublinters
  - refactor and make more simple and robust megacheck
  merging/optimizing
  - improve handling of unknown linter names in //nolint directives
  - minimize diff of our megacheck version from the upstream,
  https://github.com/golang/go/issues/29612 blocks usage of the upstream
  version
  - support the new `stylecheck` linter
  - improve tests coverage for megacheck and nolint related cases
  - update and use upstream versions of unparam and interfacer instead of forked
  ones
  - don't use golangci/tools repo anymore
  - fix newly found issues after updating linters

Also should be noted that megacheck works much faster and consumes less
memory in the newest release, therefore golangci-lint works noticeably
faster and consumes less memory for large repos.
