This introduces new APIs for memory management hardware which
are not traditionally associated with an architecture (e.g.
MMU on ARM and x86) and thus not implemented in architecture
code.

Introduce a hidden kconfig CONFIG_KERNEL_VM_SUPPORT which
enables some kconfigs that are required for virtual memory
support. CONFIG_KERNEL_VM_BASE, CONFIG_KERNEL_VM_OFFSET,
and CONFIG_KERNEL_VM_SIZE are moved under this new kconfig
so these can be enabled independent of CONFIG_MMU.

This moves CONFIG_MMU and its children from arch/Kconfig into
kernel/Kconfig. These are used to enable kernel support of MMU
so they should be under kernel/.

There is no need to use conditional compilation for the function
prototypes in the kernel architecture header file. So remove it.

When CONFIG_KERNEL_COHERENCE=y, it's not legal to place shared data
(like the queue elements in this test case) on the stack, because that
memory is incoherent with respect to other CPUs in the system.
Make them static (another option would have been to mark the test case
1cpu).

Moved conditional inclusion of tracing_tracerecorder.h
from the start of tracing.h to the bottom. This was the
initial placement of this include but it was moved as
part of PR #40126. If this file is included at the
start of tracing.h the TraceRecorder module hooks
will not map correctly and completely breaks
that module.

This PR include 2 changes to refine the testcases:
1. Now we using IPI to trigger interrupt in testing instead of INT
instruction, this means we don't need to hardcode the vector
number. That can avoid some problem.
Fixes: #40374
2. Refined the test cases. Tigger interrupt by INT instruction and
IPI cannot be masked by irq_disabled(). Unless it's a external
interrupt, such as a timer. Now remove those incorrect part of
these testcases.

For x86, make the testing purpose trigger_irq() function to send
interrupt processor interrupt to CPU by APIC, instead of executing
INT instruction. Doing this because:
1. It can be controlled by irq lock, more close to trigger irq.
2. We don't need to hardcode the interrupt vector.

It depends on a lot of factors but at least we can use this sample as a

Avoid result overflow due to intermediate product overflow.
Algorithm was multiplying input value by target frequency
before dividing it by source frequency. If target frequency was
high (e.g. conversion to nanoseconds) it could easily lead to
overflow even though final result would not overflow. Adjusting
algorithm to avoid that.
Note, that typically this code is resolved at compile time so
it will not impact performance as long as it can be resolved.
