Anas Nashif a518f48796 clock: renmae z_timeout_end_calc -> sys_clock_timeout_end_calc
Do not use z_ for internal APIs, z_ is for private APIs within one
subsystem only.

Maximilian Bachmann 34d7c78f4f kernel: add k_heap_aligned_alloc
k_heap did not have an aligned alloc function, even though
this is supported by the internal sys_heap.

Andy Ross 3c2c1d85b0 kernel: Remove z_mem_pool wrapper internals
These implemented a k_mem_pool in terms of the now universal k_heap
utility.  That's no longer necessary now that the k_mem_pool API has
been removed.

Andy Ross 6965cf526d kernel: Deprecate k_mem_pool APIs
Mark all k_mem_pool APIs deprecated for future code.  Remaining
internal usage now uses equivalent "z_mem_pool" symbols instead.

Fixes #24358

Andy Ross 8a6aee9cac kernel: Make the "heap" backend to mem_pool default
Remove the MEM_POOL_HEAP_BACKEND kconfig, treating it as true always.
Now the legacy mem_pool cannot be enabled and all usage uses the
k_heap/sys_heap backend.

Tomasz Bursztyka e18fcbba5a device: Const-ify all device driver instance pointers
Now that device_api attribute is unmodified at runtime, as well as all
the other attributes, it is possible to switch all device driver
instance to be constant.

A coccinelle rule is used for this:

@r_const_dev_1
  disable optional_qualifier
@
@@
-struct device *
+const struct device *

@r_const_dev_2
 disable optional_qualifier
@
@@
-struct device * const
+const struct device *

Fixes #27399

Andy Ross 8f0959c7b1 kernel: Add k_mem_pool compatibility layer on top of k_heap
Add a shim layer implementing the legacy k_mem_pool APIs backed by a
k_heap instead of the original implementation.

Andy Ross 0dd83b8c2e kernel: Add k_heap synchronized memory allocator
This adds a k_heap data structure, a synchronized wrapper around a
sys_heap memory allocator.  As of this patch, it is an alternative
implementation to k_mem_pool() with somewhat better efficiency and
performance and more conventional (and convenient) behavior.

Note that commit involves some header motion to break dependencies.
The declaration for struct k_spinlock moves to kernel_structs.h, and a
bunch of includes were trimmed.
