Adds beginning ProcessReader implementation for Fuchsia which currently only reads modules from the target process. ModuleSnapshotFuchsia implemented enough to pull out CrashpadInfo, which in turn is passed through ProcessSnapshotFuchsia, which is enough to get CrashpadInfoClientOptions.OneModule to pass. Bug: crashpad:196 Change-Id: I92b82696c464a5ba2e0db2c75aa46fd74b0fa364 Reviewed-on: https://chromium-review.googlesource.com/910324 Commit-Queue: Scott Graham <scottmg@chromium.org> Reviewed-by: Mark Mentovai <mark@chromium.org>
