Merge tag 'accel-20240426' of https://github.com/philmd/qemu into staging

Accelerators patches

A lot of trivial cleanups and simplifications (moving methods around,
adding/removing #include statements). Most notable changes:

- Rename NEED_CPU_H -> COMPILING_PER_TARGET
- Rename few template headers using the '.h.inc' suffix
- Extract some definitions / declarations into their own header:
  - accel/tcg/user-retaddr.h (helper_retaddr)
  - include/exec/abi_ptr.h (abi_ptr)
  - include/exec/breakpoint.h (CPUBreakpoint, CPUWatchpoint)
  - include/exec/mmu-access-type.h (MMUAccessType)
  - include/user/tswap-target.h (tswapl, bswaptls)
