Initial changes to support debugging PE/COFF files with LLDB on Windows through DIA SDK.
There is another set of changes required on the LLDB side before this does anything.

Summary:
We were treating the GUIDs in TypeServer2Record as strings, and the
non-ASCII bytes in the GUID would not round-trip through YAML.
We already had the PDB_UniqueId type portably represent a Windows GUID,
but we need to hoist that up to the DebugInfo/CodeView library so that
we can use it in the TypeServer2Record as well as in PDB parsing code.

Summary:
There is a reserved range of type indexes for built-in types (like integers).
This will create a symbol for a built-in type if the caller askes for one by
type index. This is also plumbing for being able to recall symbols by type
index in general, but user-defined types will come in subsequent patches.

All NativeRawSymbols will have a unique symbol ID (retrievable via
getSymIndexId). For now, these are initialized to 0, but soon the
NativeSession will be responsible for creating the raw symbols, and it will
assign unique IDs.
The symbol cache in the NativeSession will also require the ability to clone
raw symbols, so I've provided implementations for that as well.

This reworks the way virtual bases are handled, and also the way
padding is detected across multiple levels of aggregates, producing
a much more accurate result.

Previously the dumping of class definitions was very primitive,
and it made it hard to do more than the most trivial of output
formats when dumping. As such, we would only dump one line for
each field, and then dump non-layout items like nested types
and enums.
With this patch, we do a complete analysis of the object
hierarchy including aggregate types, bases, virtual bases,
vftable analysis, etc. The only immediately visible effects
of this are that a) we can now dump a line for the vfptr where
before we would treat that as padding, and b) we now don't
treat virtual bases that come at the end of a class as padding
since we have a more detailed analysis of the class's storage
usage.
In subsequent patches, we should be able to use this analysis
to display a complete graphical view of a class's layout including
recursing arbitrarily deep into an object's base class / aggregate
member hierarchy.

This should work on all platforms now that r299006 has landed. Tested locally
on Windows and Linux.
This moves exe symbol-specific method implementations out of NativeRawSymbol
into a concrete subclass. Also adds implementations for hasCTypes and
hasPrivateSymbols and a simple test to ensure the native reader can access the
summary information for the executable from the PDB.

Reverting until I can figure out the root cause.
Revert "Re-land: Make NativeExeSymbol a concrete subclass of NativeRawSymbol [PDB]"
This reverts commit f461a70cc376f0f91c8b4917be79479cc86330a5.

The new test should pass on all platforms now that llvm-pdbdump has the
`-color-output` option.

Together, these allow lldb-pdbdump to list all the modules from a PDB using a
native reader (rather than DIA).
Note that I'll probably be specializing NativeRawSymbol in a subsequent patch.

This allows the ability to call IPDBSession::getGlobalScope with a NativeSession and
to then query it for some basic fields from the PDB's InfoStream.
Note that the symbols now have non-const references back to the Session so that
NativeRawSymbol can access the PDBFile through the Session.

This is a stub for a new concrete implementation of IPDBRawSymbol.
Nothing uses this uses this implementation yet. My plan is to
locally switch lldb-pdbdump from the DIA reader to the Native one
and flesh out the implementations of these method stubs in the order
they're needed.
