The lp5569 controller supports auto-increment for its registers. This is by
default enabled in the chip, but the driver actively disabled it.
Since auto-increment is useful for writing multiple consecutive registers,
enable the feature. The driver, however, doesn't perform such consecutive
writes and thus the existing behavior is not altered.

`_current` is now functionally equals to `arch_curr_thread()`, remove
its usage in-tree and deprecate it instead of removing it outright,
as it has been with us since forever.

Add the following arch-specific APIs:
- arch_curr_thread()
- arch_set_curr_thread()
which allow SMP architectures to implement a faster "get current
thread pointer" than the default provided by the kernel. The 'set'
function is required for the 'get' to work, more on that later.
When `CONFIG_ARCH_HAS_CUSTOM_CURRENT_IMPL` is selected, calls to
`_current` & `k_sched_current_thread_query()` will be redirected to
`arch_curr_thread()`, which ideally should translate into a single
instruction read, avoiding the current
"lock > read CPU > read current thread > unlock" path in SMP
architectures and thus greatly improves the read performance.
However, since the kernel relies on a copy of the "current thread"s on
every CPU for certain operations (i.e. to compare the priority of the
currently scheduled thread on another CPU to determine if IPI should be
sent), we can't eliminate the copy of "current thread" (`current`) from
the `struct _cpu` and therefore the kernel now has to invoke
`arch_set_curr_thread()` in addition to what it has been doing. This
means that it will take slightly longer (most likely one instruction
write) to change the current thread pointer on the current
CPU.

The main problem of MBEDTLS_PSA_CRYPTO_LEGACY_RNG is that it
brings in some legacy modules (entropy + ctr_drbg/hmac_drbg)
which means extra ROM/RAM footprint.
MBEDTLS_PSA_CRYPTO_EXTERNAL_RNG instead simply calls to the
CSPRNG which makes it definitely smaller.

The LVGL flush thread was hard-coded to be cooperative.
For long-running actions like data transfer to the display,
this is problematic as it might block high-frequency actions like
USB or input events.
Hence, make it configurable to be preemptive, and rename it to match the
similar Kconfig values like CONFIG_SDL_THREAD_PRIORITY.

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.

Currently, every write has to be presented to the user immediately,
which negates the advantage of latched displays to prevent frame tearing.

is the last call of the frame or not, allowing displays to group writes
to a single present.
