<!--LLVM PR SUMMARY COMMENT-->

Author: Jacob Lalonde (Jlalond)

<summary>Changes</summary>

This PR adds support for `obj2yaml` and `yaml2obj` to generate minidumps that have a Memory64List stream. This is a prerequisite to #<!-- -->101086.

Worth noting
- const dropped on minidumps so we could cache a MemoryDescriptor_64 to it's actual offset, preventing the need to loop multiple times
- doesn't reuse the existing `ListStream` code in some places, because the Memory64List has a different width size field (unsigned 64), and a larger header than all the other streams. I determined refactoring the existing code to support Mem64 would be worse than supporting the special case.
