  [DebugInfo] Update CodeView enums (#71038)

This adds the following values to the CodeView.h enums (and updates the
various functions that use them):


* CPUType:
  * Added `Unknown`
* This is not currently documented in the online documentation, but this
is present in `cvconst.h` in the latest DIA SDK (Visual Studio 2022,
17.7.6)
* `Unknown` is the CPUType that is emitted by `aliasobj.exe` in the
Compile3Sym records, and can be found in objects that link with
`oldnames.lib`

* SourceLanguage (All of these are documented at
https://learn.microsoft.com/en-us/visualstudio/debugger/debug-interface-access/cv-cfl-lang?view=vs-2022
and are present in `cvconst.h` in the latest DIA SDK (Visual Studio
2022, 17.7.6))
  * Added Go
  * Added AliasObj
* emitted by `aliasobj.exe` in certain records, can be found in PDBs
that link with `oldnames.lib`
  * Changed Swift to the official Microsoft enumeration
  * Added `OldSwift`
* The old Swift enumeration of `S` was changed to `OldSwift` to allow
pdb dumping utilities to continue to emit correct source language
information for old PDBs
 
### WARNING
The `Swift` change is a potentially breaking change, as the swift
compiler will now emit `0x13` for the SourceLanguage type in PDB records
instead of `S`. This could potentially break utilities that relied on
the old enum value.
 
 * CallType
   * Added Swift
* This is not currently documented in the online documentation, but this
is present in `cvconst.h` in the latest DIA SDK (Visual Studio 2022,
17.7.6)
