Use target_info->page_bits_init to implement
migration_legacy_page_bits. Because this is the last
function within the file, rename page-vary-target.c
to page-vary-system.c and build once for system mode.

Remove the need of per-target QEMU_ARCH. Define the
QEMU_ARCH_* constants based on SYS_EMU_TARGET_* ones,
themselves already exposed via target_arch(), allowing
to check the current target is included in @arch_bitmask.

qemu_arch_available() is used to check if a broadly available
feature should be exposed to a particular set of target
architectures. Here we only want to check something that is
specific to s390x: the target_s390x() helper is more adapted.
Besides, it will allow to reduce qemu_arch_available() scope.

qemu_arch_available() is used to check if a broadly available

Since its argument is a mask of bits, rename it as @arch_bitmask.
We have less than 32 target architectures so far, so restrict it
to the uint32_t type.

We don't need translation-block.h as the TB flags are local and the

Finally tidy up the order to keep things together with the local cpu.h

Implement the gdb_get_register() helper and call it before the
regular get_monitor_def() one. Registers is exposed via the
GDB XML files will be directly handled, possibily allowing new
registers added to XML files to be automatically accessible in
QEMU monitor. All targets having GDB XML files can now be used
within the monitor.
For example with Loongarch, before:
$ qemu-system-loongarch64 -M virt -S -monitor stdio
QEMU 10.2.0 monitor - type 'help' for more information
(qemu) info registers
CPU#0
PC=000000001c000000 FCSR0 0x00000000
...
(qemu) p/x $pc
unknown register
Try "help p" for more information
(qemu)
and after:
$ ./qemu-system-loongarch64 -M virt -S -monitor stdio
QEMU 10.2.50 monitor - type 'help' for more information
(qemu) p/x $pc
0x1c000000
(qemu)
Similarly RISC-V:
QEMU 10.2.0 monitor - type 'help' for more information
(qemu) p/x $pc
unknown register
Try "help p" for more information
VS
QEMU 10.2.50 monitor - type 'help' for more information
(qemu) p/x $pc
0x1000
(qemu)
