Use the UUID from the minidump's CodeView Record for placeholder modules

This change adds support for two types of Minidump CodeView records:

PDB70 (reference: https://crashpad.chromium.org/doxygen/structcrashpad_1_1CodeViewRecordPDB70.html)
This is by far the most common record type.

ELF BuildID (found in Breakpad/Crashpad generated minidumps)
This would set a proper UUID for placeholder modules, in turn enabling
an accurate match with local module images.
