For tracing_user, the sys_trace_isr_enter() & sys_trace_isr_exit()
block any nest interrupts & most SMP interrupts for the user. It is
hard to analyze the IRQ preemption(e.g., each IRQ counter and execution
time). This commit adds ISR nest level for each CPU to the user instead
of blocking user call back when nest interrupts.

`tracing_user.h` lost several definitions, which made
CONFIG_TRACING_USER build fail. This fixes the TRACING_USER
config & adds it to the test case.
Moreover, the idle task stack is overflow on qemu_x86, qemu_cortex_m0 &
qemu_riscv64. This makes the test fail. So this commit sets the idle
stack size to 2048 for this sample to avoid it.

Adds two routines to flush pipe objects:
k_pipe_flush()
- This routine flushes the entire pipe. That includes both
the pipe's buffer and all pended writers. It is equivalent
to reading everything into a giant temporary buffer which
is then discarded.
k_pipe_buffer_flush()
- This routine flushes only the pipe's buffer (if it exists).
It is equivalent to reading a maximum of "buffer size" bytes
into a temporary buffer which is then discarded.

Added heap reference parameter to k_free tracing
hook to allow tracing of the pointer which was
passed as a parameter to a k_free call.
As part of this update the defines
(for this hook) in the various tracing formats
was also updated.

Threads may wait on an event object such that any events posted to
that event object may wake a waiting thread if the posting satisfies
the waiting threads' event conditions.
The configuration option CONFIG_EVENTS is used to control the inclusion
of events in a system as their use increases the size of
'struct k_thread'.

Create a new tracing option TRACING_USER that allows
the user to define certain user_sys_trace_... functions
to perform whatever work desired for tracing when
tasks are swiched in/out, during isr enter/exit, and when
cpu is idle.
This infrastructure can be useful for plugging into
locally defined tracing tools or any user-specific
debugging environment.
