Although there is nothing wrong with the existing code,
it doesn't permit individual bits to be set (or cleared).
This makes further changes slightly awkward.
Use a mask to restrict the bits set in an event.

Due to the limitation of the current x86 EFI cosnole implementation,
we skip hte printk which is called by tracing API:
sys_trace_thread_switched_in_user/out_user.

In order to bring consistency in-tree, migrate all subsystems code to
the new prefix <zephyr/...>. Note that the conversion has been scripted,
refer to zephyrproject-rtos#45388 for more details.

The thread switching hooks are invoked in the middle of thread
switching, after the out-going thread registers are saved, but before
the in-coming thread registers are restored, and also before
z_thread_entry is called if the thread is just starting.
When the core is first starting, the TLS base register won't be set at
all, so accessing variables will fault. When switching threads, the
in-coming thread TLS base register will not have been restored, so the
z_tls_current value will end up getting the out-going thread instead.
To fix this, switch from k_current_get() to z_current_get().

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.

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.
