v0.25.14: rename Drive raw-read API to remove third-party project breadcrumbs

Pure rename pass — no behavioral change:
- Drive::is_libredrive_active() → Drive::is_raw_read_active()
- PlatformDriver::is_libredrive_active() trait method (same rename)
- Mt1959 struct field libredrive_active → raw_read_active
- Error::AacsLibredriveUnsupported → Error::AacsRawReadUnsupported
  (numeric code E7016 unchanged)
- All callers, tests, and doc comments updated to the new name.

Old identifiers removed entirely; downstream consumers must update.
Mirrored in bdemu, freemkv, autorip, freemkv-tools.
