104714394f kernel: Introduce K_MEM_SLAB_DEFINE_STATIC
As the already existing macro K_MEM_SLAB_DEFINE results in
two variable definitions, the preceding static modifier leads to
a seemingly working solution, though linkage conflicts will occur
when the same memory slab name is used across multiple modules.

The new K_MEM_SLAB_DEFINE_STATIC macro duplicates the functionality of
K_MEM_SLAB_DEFINE with the difference that the static keywords are
internally prepended before both variable definitions.

The implementation has been tested on my Zephyr project (the build
issue faded out). The documentation has been updated altogether
with all incorrect occurences of static K_MEM_SLAB_DEFINE.

7a22a4bdf6 heap: clean up some size related issues
First, the maximum heap size must fit in 31 bits worth of chunks
because the internal 32-bit field holding the size is shared with
the `used` bit.

Then the mention of a 256-byte block in the doc is no longer
relevant. That pertained to the previous allocator implementation.

And ditto for the HEAP_MEM_POOL_MIN_SIZE kconfig option.

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.

c79d2ce794 doc: update struct references to use :c:struct:
Sphinx>=3.0 includes the `struct` role in the C domain, which provides a
specific way to link to structs, while the old :c:type: role should be
primary used to typedefs. Update existing references, using :c:type:,
:cpp:type: or emphasized symbols that point to structs to use the new
role.

53fd5ff236 doc: update function references to use :c:func:
Following the change to use the C domain for parsing, update all
existing :cpp:func: references to :c:func:. Remove the parentheses as
well, if used, because they are not needed, this is already known to be
a function, and how it is displayed in the documentation later is a
semantic decision done by the output builder.

db36b146e1 kernel: Remove supported size comments from HEAP_MEM_POOL_SIZE
The mempool implementation doesn't require specific sizes and can
support arbitrary sizes up to the limit of available memory. The
Kconfig documentation on this configuration was confusing user.

984bfae831 global: Remove leading/trailing blank lines in files
Remove leading/trailing blank lines in .c, .h, .py, .rst, .yml, and
.yaml files.

Will avoid failures with the new CI test in
https://github.com/zephyrproject-rtos/ci-tools/pull/112, though it only
checks changed files.

Move the 'target-notes' target in boards/xtensa/odroid_go/doc/index.rst
to get rid of the trailing blank line there. It was probably misplaced.
