To avoid type conflicts between the `pthread_rwlockattr_t` definition in RIOT's `pthread` implementation and newlibc's `sys/_pthreadtypes.h`, the macro `_POSIX_READER_WRITER_LOCKS` must be undefined.
The cleanup reduces the number of linker scripts used for the ESP32x ROMs and thus the symbols used from the ESP32x ROMs. It works with both gcc 12.2 and gcc 14.2. The latter gcc version is a prerequisite for ESP-IDF v5.2 and higher and thus a prerequisite for starting the work on the RIOT-OS port for the latest version of ESP-IDF.

There is clearly no reason `cpu.h` should `#include <stdio.h>`.
Also add an export pragma to `cpu_conf.h`, as portable code is
expected to include `cpu.h` (which exists across MCU families in RIOT),
and not `cpu_conf.h` (which only exists for some MCU families).
Using `PROGRAMMER=bmp` has been proven to work reliably at least on
SAMD21, SAMD5x and SAML21.
Since using unsupported programmers is treated as a warning, this change
only reduces the noise in the shell a bit and is not a functional
change.

For the other MCUs, we take the input register state instead of the
output register state when the pin is configured as input. Let's do
the same here, as this is a lot more useful and intuitive.
It turns out that the legacy GPIO API and GPIO LL may disagree on what
the GPIO base address is: GPIO LL will use the IOBUS as base address
no matter what, the legacy GPIO API will use the APB as base address
unless `periph_gpio_fast_read` is used.
If the APIs disagree, we need to do impedance matching.
This adds a delay between enabling the ADC and starting to sample
on the SAMD5x MCUs when the internal bandgap reference is used.

This changes the API of xfa from
XFA(array_name, prio) type element_name = INITIALIZER;
to
XFA(type, array_name, prio) element_name = INITIALIZER;
this allows forcing natural alignment of the type, fixing failing tests
on `native64`.
Since https://github.com/RIOT-OS/RIOT/pull/20935 gpio_write()
uses a `bool` instead of an `int`. This does the same treatment for
`gpio_read()`.
This does indeed add an instruction to `gpio_read()` implementations.
However, users caring about an instruction more are better served with
`gpio_ll_read()` anyway. And `gpio_read() == 1` is often seen in
newcomer's code, which would now work as expected.
