Expose marked content IDs for images and alt text.
- Adds two new public bits of API: - StructElement_GetMCID(STRUCTELEMENT) to return the marked content ID of the struct element. - IMAGEOBJ_METADATA.mcid to contain the marked content ID of the image. - Restores ContentMark::GetMCID, which was removed with other dead code in https://pdfium-review.googlesource.com/c/pdfium/+/19170. - Adds a couple calls to tests, including a simple new PDF to test the struct tree marked content ID.
