chg: dev: Set name for all the isc_mem context from isc_mem_create()

Instead of giving the memory context names with an explicit call to
isc_mem_setname(), add the name to isc_mem_create() call to have all the
memory contexts an unconditional name.

Merge branch 'ondrej/ondrej-isc_mem_create-with-name' into 'main'

See merge request isc-projects/bind9!10426
