This commit adds an additional test case for several kernel test suites
to ensure that the linker script generator is working correctly for a
subset of the Zephyr test suites.
The ensures that the basic functionality of the linker script generator
is working while still keep the performance impact on CI at a minimal
level.
Using the kernel tests is a trade-off between testing coverage of the
linker script generator and the time it takes to complete CI.
The kernel tests is considered to have the broadest coverage of various
features important for the generated linker script.

Move to CMake 3.20.0.
At the Toolchain WG it was decided to move to CMake 3.20.0.
The main reason for increasing CMake version is better toolchain
support.
Better toolchain support is added in the following CMake versions:
- armclang, CMake 3.15
- Intel oneAPI, CMake 3.20
- IAR, CMake 3.15 and 3.20

The default CONFIG_APIC_TIMER_IRQ_PRIORITY is 4, but it should be 1 for
ACRN. That's why the testcase failed due to no timer interrupt was
triggered.
And we also temporary adjust the testing IRQ for dynamic isr due to it
conflict with the IRQ of the APIC TSC deadline TIMER.

Every va_start() currently triggers a FPU access trap if FPU is not
already used. This is due to the fact that va_start() must copy FPU
registers that are used for float argument passing into the va_list
object. Flushing the FPU context to its owner and granting access to
the current thread is wasteful if this is only for va_start(),
especially since in most cases there are simply no FP arguments
being passed by the caller.
This is made even worse with exception code (syscalls, IRQ handlers,
etc.) where the exception code has to be resumed with interrupts
disabled upon FPU access as there is no provision for preserving an
interrupted exception mode's FPU context.
Fix those issues by simply simulating the sequence of STR instructions
that the va_start() generates without actually granting FPU access.
We limit ourselves only to exception context to keep changes to a
minimum for now.
This also allows for reverting the ARM64 exception in the nested IRQ
test as it now works properly even if FPU_SHARING is enabled.

Add test cases of direct interrupt for arch x86 and posix.
We register two direct interrupt at build time, then triggering
interrupt and check if ISR handler has executed or not. We also
check irq_enable and irq_disable works.
Why we add an extra compiler option "-mgeneral-regs-only" to make
it works in arch x86. because there might be some existing x87
instructions executing inside interrupt context.

This adds FPU sharing support with a lazy context switching algorithm.
Every thread is allowed to use FPU/SIMD registers. In fact, the compiler
may insert FPU reg accesses in anycontext to optimize even non-FP code
unless the -mgeneral-regs-only compiler flag is used, but Zephyr
currently doesn't support such a build.
It is therefore possible to do FP access in IRS as well with this patch
although IRQs are then disabled to prevent nested IRQs in such cases.
Because the thread object grows in size, some tests have to be adjusted.

'3' is the minimum BPR value leading to group and sub-group priority

Hence to be generic priority values should be above '0x0f'.

Kernel timeouts have always been a 32 bit integer despite the
existence of generation macros, and existing code has been
inconsistent about using them. Upcoming commits are going to make the
timeout arguments opaque, so fix things up to be rigorously correct.
Changes include:
+ Adding a K_TIMEOUT_EQ() macro for code that needs to compare timeout
values for equality (e.g. with K_FOREVER or K_NO_WAIT).
+ Adding a k_msleep() synonym for k_sleep() which can continue to take
integral arguments as k_sleep() moves away to timeout arguments.
+ Pervasively using the K_MSEC(), K_SECONDS(), et. al. macros to
generate timeout arguments.
+ Removing the usage of K_NO_WAIT as the final argument to
K_THREAD_DEFINE(). This is just a count of milliseconds and we need
to use a zero.
This patch include no logic changes and should not affect generated
code at all.

This commit disables the nested interrupt test for the RISC-V platform,
as interrupt nesting is not supported on the current RISV-C
architecture port.
Furthermore, the current `trigger_irq` implementation for RISC-V is
mostly incorrect and cannot be used, so there is no point in leaving
that in the codebase (see #23593).

The current nested interrupt test implementation is both buggy and
fundamentally flawed because it does not trigger a higher priority
interrupt from a lower priority interrupt context and relies on the
system timer interrupt, which is not fully governed by the test;
moreover, the current implementation does not properly validate the
test results and can report success if no interrupt is triggered and
serviced at all.
This commit reworks this test to have the following well-defined
and logical procedure:
1. [thread] Trigger IRQ 0 (lower priority)
2. [isr0] Set ISR 0 result token and trigger IRQ 1 (higher priority)
3. [isr1] Set ISR 1 result token and return
4. [isr0] Validate ISR 1 result token and return
5. [thread] Validate ISR 0 result token
The reworked test scenario ensures that the interrupt nesting works
properly and any abnormal conditions are detected (e.g. interrupts not
triggering at all, or ISR 1 not being nested under ISR 0).

Using find_package to locate Zephyr.
Old behavior was to use $ENV{ZEPHYR_BASE} for inclusion of boiler plate
code.
Whenever an automatic run of CMake happend by the build system / IDE
then it was required that ZEPHYR_BASE was defined.
Using ZEPHYR_BASE only to locate the Zephyr package allows CMake to
cache the base variable and thus allowing subsequent invocation even
if ZEPHYR_BASE is not set in the environment.
It also removes the risk of strange build results if a user switchs
between different Zephyr based project folders and forgetting to reset
ZEPHYR_BASE before running ninja / make.

The author of this test case seems to have been under the
mistaken impression that interrupts are locked in ISRs, which
is untrue.
The only reason this ever passed, anywhere, was a race between
the timer firing and the zassert_not_equal() check in
offload_function. If the busy_wait call is moved after the timer
is started, this fails everywhere.
We do not re-use the timer object from the previous case,
resolving some crashes observed on riscv.
