Use isar feature tests instead of feature bit tests.
Although none of QEMUs current cpus have VFPv3 without D32,
replace the large comment explaining why with one line that
sets ARM_HWCAP_ARM_VFPv3D16 under the correct conditions.
Mirror the test sequence used in the linux kernel.

All remaining tests for VFP4 are for fused multiply-add insns.
Since the MVFR1 field is used for both VFP and NEON, move its adjustment
from the !has_neon block to the (!has_vfp && !has_neon) block.
Test for vfp of the appropraite width alongside the test for simdfmac
within translate-vfp.inc.c. Within disas_neon_data_insn, we have
already tested for ARM_FEATURE_NEON.

We cannot easily create "any" functions for these, because the
ID_AA64PFR0 fields for FP and SIMD signal "enabled" with zero.
Which means that an aarch32-only cpu will return incorrect results
when testing the aarch64 registers.
To use these, we must either have context or additionally test
vs ARM_FEATURE_AARCH64.

The GICv2 allows the implementation to implement a variable number
of priority bits; unimplemented bits in the priority registers
are read as zeros, writes ignored. We were previously always
implementing a full 8 bits of priority, which is allowed but not
what the real hardware typically does (which is usually to have
4 or 5 bits of priority).
Add a new device property to allow the number of implemented
property bits to be specified.

I noticed this when including <liburing.h> (Linux io_uring) from

Commit a1b18df9a4 moved -m option parsing after configure_accelerators()
that broke TCG accelerator initialization which accesses global ram_size
from size_code_gen_buffer() which is equal to 0 at that moment.
Partially revert a1b18df9a4, by returning set_memory_options() to its
original location and only keep 32-bit host VA check and 'memory-backend'
size check introduced by fe64d06afc at current place.

It is possible that a ramblock doesn't have memory that QEMU can
access, this is the case with the Xen hypervisor.
In order to avoid to trigger an assert, only call ramblock_ptr() when
needed in qemu_ram_writeback(). This should fix migration of Xen
guests that was broken with bd108a44bc ("migration: ram: Switch to
