The test randomly fails on `native` due to timers being not accurate but
it cannot be otherwise. So better disable it than raising fake errors.

When CDC ACM is used as stdio the first thread in the test may have a
different ID than #3. The test code will now look at the printed thread
information (id, prio) as they are created. This avoids the need for a
table with ID/prio.

This change is a temporary patch to fix the compilation errors with the STM32 MCU implementation of the new low-level GPIO API until PR #3 for micropython is merged. Once this PR is merged, this patch can be dropped.

19270: drivers/at24cxxx: implement _mtd_at24cxxx_read_page r=benpicco a=HendrikVE

### Contribution description

The function `read_page` was missing which lead to (from a user perspective) undefined behavior on the MTD layer.

### Testing procedure

Any application using MTD in conjunction with a board with an at24cxxx.


19271: core/xfa: disable asan on llvm r=benpicco a=Teufelchen1

### Contribution description
Hi! 🦎

When using llvm and address sanitation, the XFA trip the sanitizer.
This PR attempts to fix this by adding the `no_sanitize` attribute to the XFA macros. Sadly, this attribute is not known by gnu, a guard is hence needed. I'm open for alternatives as I dislike this solution but it is the best I could come up with.

### Testing procedure

Before this patch:

Go to `examples/gnrc_minimal` and run `TOOLCHAIN=llvm make all-asan` and then `make term`.
You should see an error similar to this:
```
==3374719==ERROR: AddressSanitizer: global-buffer-overflow on address 0x080774e0 at pc 0x0804af5e bp 0x0808eb88 sp 0x0808eb78

    #3 0xf76bc7b8 in makecontext (/lib32/libc.so.6+0x4a7b8)
...
``` 
After applying this PR, the example can be build and run with llvm or gcc, with or without asan.

18392: drivers/servo: reimplement with high level interface r=benpicco a=maribu

### Contribution description

The previous servo driver didn't provide any benefit over using PWM directly, as users controlled the servo in terms of PWM duty cycles. This changes the interface to provide a high level interface that abstracts the gory PWM details.

In addition, a SAUL layer and auto-initialization is provided.

### Testing procedure

The test application provides access to the servo driver via the `saul` shell command.

Each write resulted in the MG90S servo that I connected to move to the corresponding position.
