`ssl.wrap_socket()` is deprecated in CPython, so use `SSLContext` instead,
so the example is a good example to copy.

The main changes here are to pass the address family and socket type to
`getaddrinfo()`, and then use the result of the address lookup when
creating the socket, so it has the correct address family.
This allows both IPv4 and IPv6 to work, because the socket is created with
the correct AF_INETx type for the address.
Also add some more comments to the examples to explain what's going on.
Fixes issue #15580.

Currently the stack limit margin is hard-coded in each port's call to
`mp_stack_set_limit()`, but on threaded ports it's fiddlier and can lead to
bugs (such as incorrect thread stack margin on esp32).
This commit provides a new API to initialise the C Stack in one function
call, with a config macro to set the margin. Where possible the new call
is inlined to reduce code size in thread-free ports.
Intended replacement for `MP_TASK_STACK_LIMIT_MARGIN` on esp32.
The previous `stackctrl.h` API is still present and unmodified apart from a
deprecation comment. However it's not available when the
`MICROPY_PREVIEW_VERSION_2` macro is set.

The STATIC macro was introduced a very long time ago in commit
d5df6cd44a433d6253a61cb0f987835fbc06b2de. The original reason for this was
to have the option to define it to nothing so that all static functions
become global functions and therefore visible to certain debug tools, so
one could do function size comparison and other things.
This STATIC feature is rarely (if ever) used. And with the use of LTO and
heavy inline optimisation, analysing the size of individual functions when
they are not static is not a good representation of the size of code when
fully optimised.
So the macro does not have much use and it's simpler to just remove it.
Then you know exactly what it's doing. For example, newcomers don't have
to learn what the STATIC macro is and why it exists. Reading the code is
also less "loud" with a lowercase static.
One other minor point in favour of removing it, is that it stops bugs with
`STATIC inline`, which should always be `static inline`.
Methodology for this commit was:
1) git ls-files | egrep '\.[ch]$' | \
xargs sed -Ei "s/(^| )STATIC($| )/\1static\2/"
2) Do some manual cleanup in the diff by searching for the word STATIC in
comments and changing those back.
3) "git-grep STATIC docs/", manually fixed those cases.
4) "rg -t python STATIC", manually fixed codegen lines that used STATIC.

Obtaining the stack-top via a few function calls may yield a pointer which
is too deep within the stack. So require the user to obtain it from a
higher level (or via some other means).

This makes no difference when files are linked directly into a target
application, but on macOS additional steps are needed to index common
symbols in static libraries. See https://stackoverflow.com/a/26581710
By not creating any common symbols, this problem is bypassed.
This will also trigger linker errors if there are cases where the same
symbol is defined in the host application.

It's not supported on all ports, adds complexity to the build to generate
pins_af.py, and can mostly be replicated just by printing the pin objects.

These files all use decorators (@asm_thumb, @asm_pio) that add names to the
function scope, that the linter cannot see.
It's useful to clear them in the file not in pyproject.toml as example code
will be copied and adapted elsewhere, and those developers may also use
Ruff (we hope!)

This ensures the same number of cycles are used for LED on and LED off in
