zephyr: lis2dw12: Add tests for set_power_mode()
* Export set_power_mode() in case of unit tests. We need direct access
to this function in order to exercise all of this cases, because it
is only ever called within the driver using fixed args that don't hit
all cases.
* Rename set_power_mode() to lis2dw12_set_power_mode to prevent naming
collisions
* Add a test
BRANCH=None
BUG=b:200046770
TEST=zmake -D configure --test test-drivers; make runhosttests
