Charlie Marsh 21aa552e87 Add a line-ending preservation mode to apply_patch (#37757) ...

## Why

Updating a file with `apply_patch` historically normalized its contents to LF,
which can rewrite line endings outside the requested change.

## What changed

- Add an opt-in `PreserveLineEndings` update mode and thread it through patch
  verification, application, and the standalone executable. Existing APIs keep
  the LF-normalizing mode by default.
- Retain the original endings of untouched and context lines, including in
  mixed-ending files, and use the file's first line ending for inserted or
  replaced lines.
- Track patch context separately from identical changed lines so preservation
  does not alter replacement ordering or matching.

## Testing

Add coverage for CRLF, CR, mixed endings, trailing blank lines, repeated lines,
EOF overlap rejection, and legacy LF normalization.
