Handle segfaults while walking native heap Vendor blobs on ryu mprotect heap pages, causing segfaults when dumping unreachable memory. Handle segfaults within HeapWalker by mapping a zero page over any unreadable pages. HeapWalker runs in the forked process, so the mapping will not affect the original process. Bug: 28269332 Change-Id: I16245af722123f2ad467cbc6f245a70666c55544 (cherry picked from commit ba5d9ff6d9674a0f1e985b49f53863045aff558d)
