hal_nordic: nrf_glue.h change mapped assert function

[koffes]

Today the mapping from NRFX_ASSERT is done like this:

#define NRFX_ASSERT(expression) assert(expression)

When we are using a different version of libc, the assert is mapped to libc and we cannot reach the zephyr assert handler and consequently, we cannot reach
assert_post_action to handle the fault as we desire.

Suggest we instead map this to __ASSERT_NO_MSG
