kgdb patches for 5.15

Changes for kgdb/kdb this cycle are dominated by a change from
Sumit that removes as small (256K) private heap from kdb. This is
change I've hoped for ever since I discovered how few users of this
heap remained in the kernel, so many thanks to Sumit for hunting
these down. Other change is an incremental step towards SPDX headers.
