cpu/riscv_common: rename cpu.h to cpu_common.h
...
To allow CPU specific definitions in `cpu.h`, `riscv_common/cpu.h` is renamed to ``riscv_common/cpu_common.h` and included in new `cpu.h` files for FE310 and GD32V.

cpu: do not auto-select ztimer_periph_rtt for sam0, fe310
...
The sam0 rtt busy loops for 180us every time an alarm is set or
the counter is read, this propagates and leads to timing errors
on ztimer_msec that are higher than > +-1msec.
The same goes for fe310.

cpu: add periph_rtt_overflow feature
...
The RTT overflow callback is not available on all RTT implementations.
This means it is either a no-op or `rtt_set_overflow_cb()` is a no-op
or it will overwrite the alarm set with `rtt_set_alarm()`.
This adds a feature to indicate that proper overflow reporting is available.

cpu/fe310: Allow using immediates for ecall arguments
...
The mv instruction (which is usually implemented as `add rd, x0, r1`) is
changed to `add rd, x0, %input`. This can either be used as a load
immediate or as an move.
The code size grows by two bytes. This because GCC does not compress the
li instruction to the compressed version (even though this is possible).
