service: tablet_allocator: avoid large contiguous vector in make_repair_plan()

Browse Source 
make_repair_plan() allocates a temporary vector which can grow larger
than our 128k basic allocation unit. Use a chunked vector to avoid
stalls due to large allocations.

Fixes #24713.

Closes scylladb/scylladb#24801

(cherry picked from commit 0138afa63b)

Closes scylladb/scylladb#24902
