19251: tests/driver_dac_dds: fix output of sine and saw functions r=benpicco a=benpicco



19254: cpu/gd32v: add periph_rtc_mem support r=benpicco a=gschorcht

### Contribution description

This PR provides the `periph_rtc_mem` support for GD32VF103.

A modified version of this driver could also be used for STM32F1.

### Testing procedure

`tests/periph_rtt` should work on any GD32V board, for example:
```
BOARD=sipeed-longan-nano make -C tests/periph_rtt flash
```
```
Help: Press s to start test, r to print it is ready
START
main(): This is RIOT! (Version: 2023.04-devel-319-gebc86-cpu/gd32v/periph_rtc_mem)

RIOT RTT low-level driver test
RTT configuration:
RTT_MAX_VALUE: 0xffffffff
RTT_FREQUENCY: 32768

Testing the tick conversion
Trying to convert 1 to seconds and back
Trying to convert 256 to seconds and back
Trying to convert 65536 to seconds and back
Trying to convert 16777216 to seconds and back
Trying to convert 2147483648 to seconds and back
All ok

Initializing the RTT driver
RTC mem OK
This test will now display 'Hello' every 5 seconds

RTT now: 1
Setting initial alarm to now + 5 s (163841)
rtt_get_alarm() PASSED
RTC mem OK
