Plumbing-only patch for Speculation Rules prefetch (M1, same-origin).
Adds the PPrefetchRecord IPDL protocol, child/parent actor skeletons,
and PWindowGlobal management. No behavior yet — Init/Cancel bodies and
SpeculationRulesManager wiring follow in subsequent parts.
- dom/ipc/PPrefetchRecord.ipdl (new): protocol definition
- dom/ipc/PrefetchIPCTypes.ipdlh (new): shared IPDL types
(SpeculativePrefetchArgs) usable by PPrefetchRecord + PWindowGlobal
- dom/ipc/PrefetchTypes.h (new): shared C++ enums (PrefetchState,
PrefetchAnonymizationPolicy, PrefetchSource) and ExchangeRecord
- dom/ipc/PrefetchRecordChild.{h,cpp} (new): content-side actor; holds
URL + anon policy
- dom/ipc/PrefetchRecordParent.{h,cpp} (new): parent-side actor; holds
prefetch record fields; empty RecvCancel/ActorDestroy
- dom/ipc/PWindowGlobal.ipdl: add 'manages PPrefetchRecord;' and
constructor message
- dom/ipc/WindowGlobalParent.{h,cpp}: add AllocPPrefetchRecordParent
- dom/ipc/moz.build: wire new sources
