Make mbedtls_psa_get_random more usable outside psa_crypto.c

In the external RNG case, don't make mbedtls_psa_get_random() a
static inline function: this would likely result in identical
instances of this function in every module that uses it. Instead, make
it a single function with external linkage.

In the non-external case, instead of a trivial wrapper function, make
mbedtls_psa_get_random a constant pointer to whichever DRBG function
is being used.
