x86: missing call to `k_mem_paging_eviction_accessed()`

[npitre]

Is your enhancement proposal related to a problem? Please describe.

Demand Paging may benefit from an LRU eviction algorithm now.
However it needs input from the low-level architecture memory fault code.
The X86 architecture lacks a call to k_mem_paging_eviction_accessed()
for the LRU algorithm to be effective.

Describe the solution you'd like

Someone well acquainted with the X86 MMU code should add that missing
call.

Describe alternatives you've considered

I've considered doing it myself but my X86 fu is way insufficient.
