fix(bundler): notarize DMG bundles

[michael-dm]

Summary

• notarize DMG artifacts in the macOS bundler after signing completes
• reuse the existing notarization auth flow and respect skip_stapling
• generalize notarization messaging so it applies to any macOS artifact path

Verification

• cargo check -p tauri-bundler

Fixes #7533

This is a breaking change, let's just keep FailedToUploadApp

Thanks for the PR! A few things:

1. we need you to sign your commits, much appreciated if you could set that up and sign all commits of this pr (requries force pushing)
2. please add a small changefile (check .changes dir)
3. [bug] DMG is not notarized #7533 says you don't have have to notarize the .app if you notarize the .dmg so maybe we should skip notarizing the .app if we know that we're also building a .dmg ?
