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

Move the syscall_handler.h header, used internally only to a dedicated
internal folder that should not be used outside of Zephyr.

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.

When a cache API function is called from userspace, this results on
ARM64 in an OOPS (bad syscall error). This is due to at least two
different factors:
- the location of the cache handlers is preventing the linker to
actually find the handlers
- specifically for ARM64 and ARC some cache handling functions are not
implemented (when userspace is not used the compiler simply optimizes
out these calls)
Fix the problem by:
- moving the userspace cache handlers to a their logical and proper
location (in the drivers directory)
- adding the missing handlers for ARM64 and ARC
