Subject: [PATCH] Suppress spurious warning about RCTCxxModule (#19880)

Summary:
<!--
  Required: Write your motivation here.
  If this PR fixes an issue, type "Fixes #issueNumber" to automatically close the issue when the PR is merged.
-->

On a relatively stock / default setup of RN on iOS you'll see the warning "Class RCTCxxModule was not exported. Did you forget to use RCT_EXPORT_MODULE()?" pop up on every launch. This change resolves that issue.

Fixes #14806 .

This supersedes PR #19794 .

Try a fresh project by following the RN iOS tutorial, and observe that there are no more warnings after making this change.
