boards: qemu: Add support for qemu_max board

This PR is the part 1 of a complete submission to ZVM. A draft of the complete PR can be found at:
#84123 ZVM : New-Generation Type 1.5 RTOS Virtualization Solution (Hypervisor)

---

What is changed?

- Added a new qemu_max board for QEMU emulation. This includes the addition of board-specific files such as Kconfig, defconfig, board.yaml and DTS files under `boards/qemu/max`.

- Added support for multi-core SMP with QEMU through the `qemu_max_qemu_max_smp` configuration and associated DTS and YAML files.

- Updated SoC-specific configurations under `soc/arm/qemu_max`, including Kconfig, SoC-specific settings, and memory regions in `mmu_regions.c`.

- Added device tree include file `qemu-virt-max.dtsi` for enhanced compatibility with the qemu_max board.

Why do we need this change?
- The qemu_max board supports the hardware features of ARMv8.1+, while the existing qemu_cortex_a53 does not.

@GueqiXie Boards: fix qemu a53 issue should not be coupled with qemu_max, it should be a single commit.
