Michael Pratt efa43c57b1 internal/runtime/maps: reuse deleted slots on insert
While walking the probe sequence, Put keeps track of the first deleted
slot it encountered. If it reaches the end of the probe sequence without
finding a match, then it will prefer to use the deleted slot rather than
a new empty slot.

For #54766.
