Curtis 'Fjord' Hawthorne 598125109d image: preserve metadata when resizing prompt images (#27266) ...

## Summary

- Preserve ICC profiles and EXIF metadata when resizing and re-encoding
prompt images.
- Retain EXIF orientation metadata without rotating or otherwise
modifying the pixel data locally.
- Support metadata preservation for PNG, JPEG, and WebP outputs.
- Continue returning the original bytes when an image does not require
re-encoding.

This intentionally preserves the metadata most important for rendering
prompt images faithfully. Other format-specific metadata is not copied.

## Motivation

Client-side resizing previously discarded image metadata during
re-encoding. This could lose color-profile information and EXIF
orientation needed by downstream image consumers.
