  1. feat: support ARCH_REMAP_KERNEL on libcpu/c906 (#9123) (#9171)

    feat: [libcpu/c906] support ARCH_REMAP_KERNEL
    
    This change was necessary to enable the remapping of the kernel image to
    a high virtual address region on the c906 platform.
    
    Changes:
    - Introduced new configuration options `ARCH_REMAP_KERNEL`, and
      `ARCH_USING_ASID` under the `ARCH_RISCV64` section.
    - Updated MMU initialization and switching functions to incorporate
      remapping handling.
    - Modified page table setup for proper memory attribute settings.
    - Added support for early memory setup, kernel remapping
    - Added conditional compilation for ASID support in the `rt_aspace` struct,
      since this is not enable currently for most architecture.
