x86: remove usage of CONFIG_KERNEL_LINK_IN_VIRT

Browse source 
There is no need to use this kconfig, as the phys-to-virt
offset is enough to figure out if the kernel is linked in
virtual address space in gen_mmu.py.

For code, use Z_VM_KERNEL instead.

* By default, the kernel is linked at its physical address and all addresses
* are in RAM.
*
* If CONFIG_KERNEL_LINK_IN_VIRT is enabled, the kernel is linked at
* the virtual address space defined by CONFIG_KERNEL_VM_BASE,
* and CONFIG_KERNEL_VM_SIZE. CONFIG_KERNEL_VM_OFFSET defines the offset of
* the start of virtual address space to place the kernel. This allows
* the kernel to have a bigger address space.
*
* If CONFIG_XIP is enabled, then another MEMORY region is declared for ROM,
* and this is where the Zephyr image is booted from. The linker LMAs and VMAs
* are set up, such that read/write data/bss have their VMA addresses
