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)

Hexagon (target/hexagon) Use QEMU decodetree (32-bit instructions)

The Decodetree Specification can be found here
https://www.qemu.org/docs/master/devel/decodetree.html

Covers all 32-bit instructions, including HVX

We generate separate decoders for each instruction class. The reason
will be more apparent in the next patch in this series.

We add 2 new scripts
gen_decodetree.py Generate the input to decodetree.py
gen_trans_funcs.py Generate the trans_* functions used by the
output of decodetree.py

Since the functions generated by decodetree.py take DisasContext * as an
argument, we add the argument to a couple of functions that didn't need
it previously. We also set the insn field in DisasContext during decode
because it is used by the trans_* functions.

There is a g_assert_not_reached() in decode_insns() in decode.c to
verify we never try to use the old decoder on 32-bit instructions
