[ reviewed by @jabraham17 ]

Previously, the bigint serialization routines were using plain
assignment of the extern `mpz` field, which would result in bad memory
accesses, since the `mpz` field had not been initialized. Switching to
`mpz_init_set` does both the initialization and assignment.

This bug was revealed by Bears-R-Us/arkouda#2437
and a test is added in #22403
for the `+ scan` over a block distributed array that was triggering
this.
