Daniel Leung 01f8e0fa2d demand_paging: eviction: add kconfig CONFIG_EVICTION_TRACKING
This adds a new kconfig for eviction algorithm which needs page
tracking. When enabled, k_mem_paging_eviction_add()/_remove()
and k_mem_paging_eviction_accessed() must be implemented.
If an algorithm does not do page tracking, there is no need to
implement these functions, and no need for the kernel MMU code
to call into empty functions. This should save a few function
calls and some CPU cycles.

Note that arm64 unconditionally calls those functions so
forces CONFIG_EVICTION_TRACKING to be enabled there.

The Zephyr Project is a scalable real-time operating system (RTOS) supporting
multiple hardware architectures, optimized for resource constrained devices,
and built with security in mind.

The Zephyr OS is based on a small-footprint kernel designed for use on
resource-constrained systems: from simple embedded environmental sensors and
LED wearables to sophisticated smart watches and IoT wireless gateways.

The Zephyr kernel supports multiple architectures, including ARM (Cortex-A,
Cortex-R, Cortex-M), Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V,
SPARC, MIPS, and a large number of `supported boards`_.
