Minimize EditText Spans 7/N: Avoid temp list

Summary:
This is part of a series of changes to minimize the number of spans committed to EditText, as a mitigation for platform issues on Samsung devices. See this [GitHub thread]( #35936 (comment)) for greater context on the platform behavior.

This change addresses some minor CR feedback and removes the temporary list of spans in favor of applying them directly.
