crypto: drbg - Move fixed values into constants

Since only one drbg_core remains, the state length, block length, and
security strength are now fixed values.  Moreover, the maximum request
length, maximum additional data length, and maximum number of requests
were all already fixed values.

Simplify the code by just using #defines for all these fixed values.

In drbg_seed_from_random(), take advantage of the constant to define the
array size.  Remove assertions that are no longer useful.

In the case of drbg_blocklen() and drbg_statelen(), replace these with a
single value DRBG_STATE_LEN, as for HMAC_DRBG they are the same thing.
