This commit adds the sections describing how the dynamic memory
management is handled to the C language support and standard library
documentations.

The kernel documentation listed the memory management API pages under
two different sections: 'Kernel/Kernel Services' and
'Kernel/Memory Management' -- this creates unnecessary confusion and
makes it hard to look up all supported kernel memory management APIs.
This commit relocates the memory management API pages under
'Kernel/Kernel Services' to 'Kernel/Memory Management' so that all
memory management APIs provided by the kernel are described in one
unified section.
The link to the 'Kernel/Memory Management' index page is still left in
the 'Kernel Services' page because it may still be helpful to look at
it as part of the services provided by the Zephyr kernel -- it is just
more substantial than the rest and deserves more visibility.

This commit adds the 'Language Support' sub-category under the
'Developing with Zephyr' category with programming language support-
related documentations.
The contents of the 'C standard library' page have been relocated to
the 'C Language Support' page, and the contents of the 'C++ Support for
Applications' page have been relocated to the 'C++ Language Support'
page.

There are no longer per-partition initialization functions.
Instead, we iterate over all of them at boot to set up the
derived k_mem_partitions properly.

have been removed from the userspace test.

The app shared memory macros for declaring domains provide
no value, despite the stated intentions.
Just declare memory domains using the standard APIs for it.
To support this, symbols declared for app shared memory
partitions now are struct k_mem_partition, which can be
passed to the k_mem_domain APIs as normal, instead of the
app_region structs which are of no interest to the end
user.

There is an effort underway to make most of the Zephyr build script's
reentrant. Meaning, the build scripts can be executed multiple times
during the same CMake invocation.
Reentrancy enables several use-cases, the motivating one is the
ability to build several Zephyr executables, or images, for instance a
bootloader and an application.
For build scripts to be reentrant they cannot be directly referencing
global variables, like target names, but must instead reference
variables, which can vary from entry to entry.
Therefore, in this patch, we replace global targets with variables.

In general driver system calls are implemented at a subsystem
layer. However, some drivers may have capabilities specific to
the hardware not covered by the subsystem API. Such drivers may
want to define their own system calls.
This macro makes it simple to validate in the driver-specific
system call handlers that not only does the untrusted device
pointer correspond to the expected subsystem, initialization
state, and caller permissions, but also that the device object
is an instance of a specific driver (and not just any driver in
that subsystem).

k_poll_signal was being used by both, struct and function. Besides
this being extremely error prone it is also a MISRA-C violation.
Changing the function to contain a verb, since it performs an action
and the struct will be a noun. This pattern must be formalized and
followed and across the project.
