Dean Michael Berris 3ce0749911 [XRay] Use a function to return a constant 
We do this instead of using static constexpr char arrays because MSVC
2015 cannot handle the constant initialisation of those along with the
out-of-line storage declaration.

This is a follow-up to D51672.

Dean Michael Berris 96ff6d8772 [XRay] Use `const` instead of `constexpr` in storage declaration 
This should make MSVC happy with the storage provided for static
constexpr character arrays out-of-line.

Follow-up to D51672.

Dean Michael Berris fbc59d92e6 [XRay] Add a RecordPrinter visitor for FDR Records 
Summary:
This change adds a `RecordPrinter` type which does some basic text
serialization of the FDR record instances. This is one component of the
tool we're building to dump the records from an FDR mode log as-is.

This is a small part of D50441.
