19341: Picolibc updates r=benpicco a=keith-packard
### Contribution description
Minor updates to picolibc support for newer versions of picolibc, including 1.8.
### Testing procedure
Here's the current build result for a board I happen to have on my bench right now:
```
$ make -C examples/blinky BOARD=nucleo-f103rb FEATURES_REQUIRED=picolibc
...
/home/keithp/src/RIOT/sys/picolibc_syscalls_default/syscalls.c:319:1: error: unknown type name '_READ_WRITE_RETURN_TYPE'
319 | _READ_WRITE_RETURN_TYPE read(int fd, void *dest, size_t count)
| ^~~~~~~~~~~~~~~~~~~~~~~
/home/keithp/src/RIOT/sys/picolibc_syscalls_default/syscalls.c:351:1: error: unknown type name '_READ_WRITE_RETURN_TYPE'
351 | _READ_WRITE_RETURN_TYPE write(int fd, const void *src, size_t count)
| ^~~~~~~~~~~~~~~~~~~~~~~
...
```
### Description of changes
1. Fix the read/write return values (Picolibc 1.8 uses POSIX standard types now)
2. Add new symbols to linker scripts (Picolibc needs help dealing with TLS alignment)
3. Align stack and thread local storage block during thread setup.
19345: cpu/riscv_common: convert to uword_t usage r=benpicco a=dylad
### Contribution description
This PR makes use of `uword_t` type in a few places in `cpu/riscv_common`.
This should not have any effect on produced binaries.
### Testing procedure
CI should be enough.
### Issues/PRs references
Quickly adapt from #16994. It will help for 64 bits support one day ;)
