[msbuild] Only sign the app bundle if codesigning is enabled. Fixes #16197.

[rolfbjarne]

Only sign the app bundle if codesigning is enabled.

This fixes a bug where we'd still try to sign an app bundle, even if the user
disabled code signing by setting EnableCodeSigning=false, if the default logic
was to sign the app bundle.

Fixes #16197.
