accel/ivpu: Refactor memory ranges logic

Browse source 
Add new dma range and change naming convention for virtual address
memory ranges managed by KMD.

New available ranges are named as follows:
 * global range - global context accessible by FW
 * aliased range - user context accessible by FW
 * dma range - user context accessible by DMA
 * shave range - user context accessible by shaves
 * global shave range - global context accessible by shave nn
