arm64: introduce KIMAGE_VADDR as the virtual base of the kernel region
This introduces the preprocessor symbol KIMAGE_VADDR which will serve as the symbolic virtual base of the kernel region, i.e., the kernel's virtual offset will be KIMAGE_VADDR + TEXT_OFFSET. For now, we define it as being equal to PAGE_OFFSET, but in the future, it will be moved below it once we move the kernel virtual mapping out of the linear mapping.
