Mark Mentovai a0f5dc62a4 Add MinidumpCrashpadInfo::simple_annotations.
Some annotations will exist at a broader scope than per-module, which is
the only place that annotations can currently be stored. The product
name and version are not under the control of any module, but are
established when the first Crashpad client establishes a handler. These
annotations will be stored in a minidump’s MinidumpCrashpadInfo
structure, which applies to the entire minidump.

Within the snapshot interface, this data is carried within the
“process” snapshot because it is the top-level structure in that family.
Note that the data may not correspond directly with a process, however.
