Fixes#4356
In XTOS SOF, ipc_send_queued_msg() is run by task_main_primary_core(),
the initialization of which has a hard and circular dependency with the
initialization of the EDF scheduler. This EDF scheduler is not part of
Zephyr. Because of the circular dependency it does not seem
possible (nor desirable?) to refactor this code and make it compatible
with Zephyr. So schedule ipc_send_queued_msg() differently in Zephyr:
using a notifier triggered by the periodic Low Latency scheduler.

To increase performance of audio application code, the SOF heap should
be mapped to cached address region on platforms with aliased
cached/uncached memory layout.
This splits the heap into two and maps the SOF_MEM_ZONE_BUFFER to
the cached heap and all rest to uncached heap.
The raw heap memory area is still mapped to uncached memory, even for
the cached heap. The allocated blocks are converted to cached addresses
and passed to SOF users of rmalloc() and rballoc_align(). To ensure
application buffers do not share cachelines with heap metadata chunks,
allocation sizes are rounded up to integer multiples of platform
cacheline size.

Commit 8357dcf793 ("zephyr: trace: use zephyr utilities when enabled")
added Zephyr's sys/printk.h in order to fix:
warning: implicit declaration of function 'printk'.
Remove #ifdef __ZEPHYR__ macro since this is not needed, because
the whole file is for Zephyr only.

Currently the DAI HW configuration is tightly bound to the IPC major
version and IPC structures. Provide a mechanism whereby different
IPC data structures can be passed for DAI configuration.
This change does the following changes.
1) Pass a common ipc_config_dai structure to all dai config call. This
allows retention of common logic that uses this common data.
2) Provide a IPC specific private data pointer to the dai config that
can be interpreted by the DAI as custom data. Today this is the
existing IPC, but it could also support an NHLT binary register blob in
the future.
3) Splits ipc specific code out of src/audio/dai.c and into
src/ipc/ipc3-dai.c.

SOF registers IRQ handlers dynamically, therefore disabling
support for dynamic interrupts for SOF builds doesn't make
much sense. However, this can be used to at least increase
compile-time testing coverage and potentially enable
applications, not using dynamic interrupt registration.

When building SOF with Zephyr for unsupported architectures
the following additional adjustments to the wrapper are required:

2. implement stubs for interrupt handlich code
3. remove arch_timer_get_system() as it's provided by a header
4. hardcode "return 0;" for platform_timer_get()
5. disable sys_module_init() which anyway isn't yet functional
under Zephyr
6. add dummy platform_init() and platform_boot_complete()
7. add log_const_sof

parity is reached when it can be deleted (as Zephyr APIs can be used
