drm/xe: Internally change the compute_mode and no_dma_fence mode naming

The name "compute_mode" can be confusing since compute uses either this
mode or fault_mode to achieve the long-running semantics, and compute_mode
can, moving forward, enable fault_mode under the hood to work around
hardware limitations.

Also the name no_dma_fence_mode really refers to what we elsewhere call
long-running mode and the mode contrary to what its name suggests allows
dma-fences as in-fences.

So in an attempt to be more consistent, rename
no_dma_fence_mode -> lr_mode
compute_mode      -> preempt_fence_mode

And adjust flags so that

preempt_fence_mode sets XE_VM_FLAG_LR_MODE
fault_mode sets XE_VM_FLAG_LR_MODE | XE_VM_FLAG_FAULT_MODE
