19743: tests/unittests: improve int size detection r=maribu a=maribu
### Contribution description
Deduce from the value of `INT_MAX` whether `int` is 16 bit or 32 bit, rather than check CPU names.
19744: tests: update tests for MSP430 CPU r=maribu a=maribu
### Contribution description
Using the builtin `__MSP430__` macro is fool-proof and stable even if one would try to rename and reorganize the MSP430 cpu code.

Checking for overflow of integer addition by comparing against one of
the arguments of the addition does not work when the result of the
addition is automatically promoted to a larger type.
Fix by using an explicit cast to make sure that the result of the
addition is not implicitly converted to a larger type.

19735: nrf5x_common: Clear I2C periph shorts r=benpicco a=bergzand
### Contribution description
The I2C peripheral's shortcuts are used with the read and write register to automatically stop the I2C transaction or to continue with the next stage.
With simple I2C read and write bytes these shorts are not used, but are also not cleared by the function in all cases, causing it to use the shortcut configuration set by a previous function call. This patch ensures that the shorts are always set by the read and write functions
### Testing procedure
Should be possible to spot with a logic analyzer and the I2C periph test. Maybe the HIL test can also detect it :)
