target/arm/hvf: Add trace.h header

The documentation for trace events says that every subdirectory which
has trace events should have a trace.h header, whose only content is
an include of the trace/trace-<subdir>.h file.

When we added the trace events in target/arm/hvf/ we forgot to create
this file and instead hvf.c directly includes
trace/trace-target_arm_hvf.h.

Create the standard trace.h file to bring this into line with the
convention.

hvf: arm: Implement and use hvf_get_physical_address_range

This patch's main focus is to use the previously added
hvf_get_physical_address_range to inform VM creation
about the IPA size we need for the VM, so we can extend
the default 36b IPA size and support VMs with 64+GB of
RAM. This is done by freezing the memory map, computing
the highest GPA and then (depending on if the platform
supports an IPA size that large) telling the kernel to
use a size >= for the VM. In pursuit of this a couple of
things related to how we handle the physical address range
we expose to guests were altered, but for an explanation of
what we were doing:

Today, to get the IPA size we were reading id_aa64mmfr0_el1's
PARange field from a newly made vcpu. Unfortunately, HVF just
returns the hosts PARange directly for the initial value and
not the IPA size that will actually back the VM, so we believe
we have much more address space than we actually do today it seems.

Starting in macOS 13.0 some APIs were introduced to be able to
query the maximum IPA size the kernel supports, and to set the IPA
size for a given VM. However, this still has a couple of issues
on < macOS 15. Up until macOS 15 (and if the hardware supported
it) the max IPA size was 39 bits which is not a valid PARange
value, so we can't clamp down what we advertise in the vcpu's
id_aa64mmfr0_el1 to our IPA size. Starting in macOS 15 however,
the maximum IPA size is 40 bits (if it's supported in the hardware
as well) which is also a valid PARange value so we can set our IPA
size to the maximum as well as clamp down the PARange we advertise
to the guest. This allows VMs with 64+ GB of RAM and should fix the
oddness of the PARange situation as well.

hvf: Split up hv_vm_create logic per arch

This is preliminary work to split up hv_vm_create
logic per platform so we can support creating VMs
with > 64GB of RAM on Apple Silicon machines. This
is done via ARM HVF's hv_vm_config_create() (and
other APIs that modify this config that will be
coming in future patches). This should have no
behavioral difference at all as hv_vm_config_create()
just assigns the same default values as if you just
passed NULL to the function.

hvf: arm: Fix encodings for ID_AA64PFR1_EL1 and debug System registers

We wrongly encoded ID_AA64PFR1_EL1 using {3,0,0,4,2} in hvf_sreg_match[] so
we fail to get the expected ARMCPRegInfo from cp_regs hash table with the
wrong key.

Fix it with the correct encoding {3,0,0,4,1}. With that fixed, the Linux
guest can properly detect FEAT_SSBS2 on my M1 HW.

All DBG{B,W}{V,C}R_EL1 registers are also wrongly encoded with op0 == 14.
It happens to work because HVF_SYSREG(CRn, CRm, 14, op1, op2) equals to
HVF_SYSREG(CRn, CRm, 2, op1, op2), by definition. But we shouldn't rely on
it.

Newer versions of the Arm ARM (e.g. rev K.a) now define fields for

fields if we need to. There's no behaviour change here since we
don't currently set the register value to non-zero.

Accelerators patches

A lot of trivial cleanups and simplifications (moving methods around,

- 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)
