Merge tag 'single-binary-20250425' of https://github.com/philmd/qemu into staging

Various patches loosely related to single binary work:

- Replace cpu_list() definition by CPUClass::list_cpus() callback
- Remove few MO_TE definitions on Hexagon / X86 targets
- Remove target_ulong uses in  ARMMMUFaultInfo and ARM CPUWatchpoint
- Remove DEVICE_HOST_ENDIAN definition
- Evaluate TARGET_BIG_ENDIAN at compile time and use target_needs_bswap() more
- Rename target_words_bigendian() as target_big_endian()
- Convert target_name() and target_cpu_type() to TargetInfo API
- Constify QOM TypeInfo class_data/interfaces fields
- Get default_cpu_type calling machine_class_default_cpu_type()
- Correct various uses of GLibCompareDataFunc prototype
- Simplify ARM/Aarch64 gdb_get_core_xml_file() handling a bit
- Move device tree files in their own pc-bios/dtb/ subdir
- Correctly check strchrnul() symbol availability on macOS SDK
- Move target-agnostic methods out of cpu-target.c and accel-target.c
- Unmap canceled USB XHCI packet
- Use deposit/extract API in designware model
- Fix MIPS16e translation
- Few missing header fixes
