  Reapply "[PDB][llvm-pdbutil] Add DXContainer support for `pdb2yaml` and `yaml2pdb`" (#200413)

This reapplies #198351 with a fix for `-Wchanges-meaning` causing an
error in `PdbYaml.h`.
Original description:

This patch enables the following:
1. Attempting to parse a `DXContainer` from stream 5 (generated by
DirectX tools) of a PDB file, to be used later in `llvm-pdbutil`.
2. Outputting a PDB file with a built in DXContainer as YAML. Existing
DirectX tools form a PDB container with empty DBI, TPI and IPI streams,
so this patch also allows them to be empty when dumping a PDB file as
YAML.
3. Creating a PDB file from YAML with an built in DXContainer. When
creating a PDB with a DXContainer, streams DBI, TPI and IPI can be
completely empty, so this patch also includes adjustments to allow
forming such a PDB file. This is done to maintain compatibility with
other DirectX tools.
