7960de99db [codeview] Add a type visitor to help abstract away type stream handling
Summary:
Port the dumper in llvm-readobj over to it.

I'm planning to use this visitor to power type stream merging.

While we're at it, try to switch from StringRef to ArrayRef<uint8_t> in some
places.

2d02ceefdc Move CodeViewTypeStream to DebugInfo/CodeView
Ability to parse codeview type streams is also needed by
DebugInfoPDB for parsing PDBs, so moving this into a library
gives us this option.  Since DebugInfoPDB had already hand
rolled some code to do this, that code is now convereted over
to using this common abstraction.

f5c59654f7 Parse the TPI (type information) stream of PDB files.
This parses the TPI stream (stream 2) from the PDB file. This stream
contains some header information followed by a series of codeview records.
There is some additional complexity here in that alongside this stream of
codeview records is a serialized hash table in order to efficiently query
the types. We parse the necessary bookkeeping information to allow us to
reconstruct the hash table, but we do not actually construct it yet as
there are still a few things that need to be understood first.
