feat(Dialog): don't override type attribute if set on mat-dialog-close

[flauc]

only default the type attribute on mat-dialog-close if it isn't set

#16909

[jelbourn]

Can you update the API gold? Just run

yarn bazel run //tools/public_api_guard:material/dialog.d.ts_api.accept

(we have golds for d.ts files to prevent public APIs from being changed inadvertently)

[flauc]

yarn bazel run //tools/public_api_guard:material/dialog.d.ts_api.accept

Done

The failing tests don't look to be related to the dialog.

I see that you just added the pr: merge ready label, but the following checks are still failing:
     status "ci/circleci: tests_browserstack" is failing

If you want your PR to be merged, it has to pass all the CI checks.

If you can't get the PR to a green state due to flakes or broken master, please try rebasing to master and/or restarting the CI job. If that fails and you believe that the issue is not due to your change, please contact the caretaker and ask for help.
