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 guide in the docs was missing references to the added tracing
syscall macro hooks. This adds those.

When CONFIG_TRACING_OBJECT_TRACKING is enabled, the kernel will keep
lists of some objects (detailed below), so that debuggers or other tools
can keep track of them.
The lists of objects are:
struct k_timer *_track_list_k_timer;
struct k_mem_slab *_track_list_k_mem_slab;
struct k_sem *_track_list_k_sem;
struct k_mutex *_track_list_k_mutex;
struct k_stack *_track_list_k_stack;
struct k_msgq *_track_list_k_msgq;
struct k_mbox *_track_list_k_mbox;
struct k_pipe *_track_list_k_pipe;
struct k_queue *_track_list_k_queue;
Note that while CONFIG_TRACING is needed, one can always use
CONFIG_TRACE_NONE=y. Also, tracking will only be done for objects that
are also being traced (so, to prevent tracking of some type of object,
such as k_timer, just make CONFIG_TRACING_TIMER=n).
Some simple "sanity checking" tests are also added in this patch.

Adds Xtensa as supported architecture for coredump. Fixes
a few typos in documentation, Kconfig and a C file. Dumps
minimal set of registers shown by 'info registers' in GDB
for the sample_controller and ESP32 SOCs. Updates tests.

Many documents relied on single quotes to create references, e.g.
`my_reference`. This is possible because `default_role = "any"` is
enabled in Sphinx conf.py. However, this method comes with its problems:
- It mixes all domains together, so it's not clear to what are you
referencing: a document? a Kconfig option? a C function?...
- It creates inconsistencies: in some places explicit roles are used
(e.g. :ref:`my_page`) while in some others not.
- _Conflictis_ with markdown. Single quotes are used for literals in
Markdown, so people tend to use the same syntax in Sphinx, even though
it has a different purpose.
Usages have been found using `git grep ' `[^`]*` ' -- **/*.rst`.

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.

features such as tracing, post mortem analysis and thread debugging
using thread analyzer.
