Adds the dump_minidump_annotations tool (modified from jperaza's WIP
code). This works similarly to Breakpad's minidump_dump tool, but:
1. Is available on Windows
2. Only dumps simple/vectored annotations and annotation objects instead
of the entire minidump contents.
Current use case for this is to be able to get a minidump's process
type on Windows without having to go through symbolization, but there
may be other use cases in the future.
