Merge bitcoin/bitcoin#25060: blockstorage: add LIFETIMEBOUND to GetFirstStoredBlock()::start_time
4cb9d214345550cb0299139b2badb73ba1e53532 blockstorage: add LIFETIMEBOUND to GetFirstStoredBlock()::start_time (Jon Atack)
Pull request description:
Suggested in https://github.com/bitcoin/bitcoin/pull/25016#discussion_r862330288, the lifetimebound attribute here indicates that a resource owned by the `start_block` param of `CBlockIndex* BlockManager::GetFirstStoredBlock()` can be retained by the method's return value, which enables detecting the use of out-of-scope stack memory (ASan `stack-use-after-scope`) at compile time.
See https://releases.llvm.org/12.0.0/tools/clang/docs/AttributeReference.html#lifetimebound and #22278 for related discussion, and #25040 for a similar example.
