Simplify tp-text property merging implementation

Browse Source 
- Add tp--merge-string-props-into-plist to merge embedded properties
  from tp-text value into props plist with proper face merging
- Simplify tp--handle-tp-text-property to use the new merge function
  and return merged props directly
- Simplify tp-set, tp-reset, tp-add by removing marker-based handling
- Fix tp-add to avoid duplicate face merging for strings with tp-text
- Remove unused tp--apply-string-props-to-region and
  tp--remove-internal-markers functions
- Update tests to match the simplified implementation
