Namespaced the generated headers with `zephyr` to prevent
potential conflict with other headers.
Introduce a temporary Kconfig `LEGACY_GENERATED_INCLUDE_PATH`
that is enabled by default. This allows the developers to
continue the use of the old include paths for the time being
until it is deprecated and eventually removed. The Kconfig will
generate a build-time warning message, similar to the
`CONFIG_TIMER_RANDOM_GENERATOR`.
Updated the includes path of in-tree sources accordingly.
Most of the changes here are scripted, check the PR for more
info.

Cache operations that act on unaligned buffers (with respect to cache
line) or buffers that are not multiple of the cache line size are at
least dangerous with an high risk of data and memory corruption.
While we do not enforce a contract on the buffer characteristics between
users and APIs, we can at least add a note in the documentation
specifying an undefined behaviour when the passed buffer is unaligned or
wrongly sized.

The current headers do not allow the full inlining of the cache
functions. Rework and cleanup the headers to allow for the full
inlining.

The cache operations must be quick, optimized and possibly inlined. The
current API is clunky, functions are not inlined and passing parameters
around that are basically always known at compile time.
In this patch we rework the cache functions to allow us to get rid of
useless parameters and make inlining easier.
In particular this changeset is doing three things:
1. `CONFIG_HAS_ARCH_CACHE` is now `CONFIG_ARCH_CACHE` and
`CONFIG_HAS_EXTERNAL_CACHE` is now `CONFIG_EXTERNAL_CACHE`
2. The cache API has been reworked.
3. Comments are added.

We have now:
- CPU_HAS_{D,I}CACHE: when the CPU has support for d-cache and i-cache
- {D,I}CACHE: to enable / disable d-cache and i-cache

In order to bring consistency in-tree, migrate all includes within
include directory to the new prefix <zephyr/...>. Note that the
conversion has been scripted, refer to zephyrproject-rtos#45388 for more
details.

Move include paths and add new target_include_directories to support
backwards compatibility:
* /include -> /include/zephyr
example: <irq.h> -> <zephyr/irq.h>
