app: 'd' — define typed data in the listing (make_data, M3)

Press 'd' on a listing head to define typed data at that address via a prompt
(the ".data type definitions" backlog item). Mirrors the retype prompt flow:
MakeDataRequested -> #makedata Input (prefilled with a size-appropriate default
type: unsigned __int8/16/32/64 or char[N]) -> _do_make_data worker ->
Program.make_data -> bump_items -> reopen the listing in place. Accepts any C
type IDA's SetType understands: int, char[16], my_struct, T *arr[4], ...

Pilot: listing_view gains a deterministic sub-test — undefine a data head to
synthesize an unknown run, assert it renders as `unknown`, then 'd' char[4]
over it and assert it becomes a `data` head. 118 pass / 1 pre-existing flaky
(filter); rpc_smoke 29/0.
