[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,

[CodeView] Add source languages ObjC and ObjC++

This patch adds llvm::codeview::SourceLanguage entries, DWARF translations, and PDB source file extensions in LLVM and allow LLDB's PDB parsers to recognize them correctly.

The CV_CFL_LANG enum in the Visual Studio 2022 documentation https://learn.microsoft.com/en-us/visualstudio/debugger/debug-interface-access/cv-cfl-lang defines:
```
CV_CFL_OBJC = 0x11,
CV_CFL_OBJCXX = 0x12,
```

Since the initial commit in D24317, ObjC was emitted as C language and ObjC++ as Masm.

Microsoft has added several new entries to the CV_CFL_LANG enum, including Rust:
https://docs.microsoft.com/en-us/visualstudio/debugger/debug-interface-access/cv-cfl-lang

This change adds Rust to the corresponding LLVM enum and translates `dwarf::DW_LANG_Rust` to `SourceLanguage::Rust` in the CodeView AsmPrinter.

This means that Rust will no longer emit as Masm.

llvm-pdbdump: Fix several smaller issues with injected source compression handling

- getCompression() used to return a PDB_SourceCompression even though
the docs for IDiaInjectedSource are explicit about the return value
being compiler-dependent. Return an uint32_t instead, and make the
printing code handle unknown values better by printing "Unknown" and
the int value instead of not printing any compression.

- Print compressed contents as hex dump, not as string.

- Add compression type "DotNet", which is used (at least) by csc.exe,
the C# compiler. Also add a lengthy comment describing the stream
contents (derived from looking at the raw hex contents long enough
to see the GUIDs, which led me to the roslyn and mono implementations
for handling this).

- The native injected source dumper was dumping the contents of the
whole data stream -- but csc.exe writes a stream that's padded with
zero bytes to the next 512 boundary, and the dia api doesn't display
those padding bytes. So make NativeInjectedSource::getCode() do the
same thing.

[COFF, ARM64] Add CodeView register mapping

CodeView has its own register map which is defined in cvconst.h. Missing this
mapping before saving register to CodeView causes debugger to show incorrect
value for all register based variables, like variables in register and local
variables addressed by register (stack pointer + offset).

This change added mapping between LLVM register and CodeView register so the
correct register number will be stored to CodeView/PDB, it aso fixed the
mapping from CodeView register number to register name based on current
CPUType but print PDB to yaml still assumes X86 CPU and needs to be fixed.

Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

[PDB] Make the native reader support enumerators.

Previously we would dump the names of enum types, but not their
enumerator values. This adds support for enumerator values. In
doing so, we have to introduce a general purpose mechanism for
caching symbol indices of field list members. Unlike global
types, FieldList members do not have a TypeIndex. So instead,
we identify them by the pair {TypeIndexOfFieldList, IndexInFieldList}.

[PDB] Support dumping injected sources via the DIA reader.

Injected sources are basically a way to add actual source file content
to your PDB. Presumably you could use this for shipping your source code
with your debug information, but in practice I can only find this being
used for embedding natvis files inside of PDBs.

In order to effectively test LLVM's natvis file injection, we need a way
to dump the injected sources of a PDB in a way that is authoritative
(i.e. based on Microsoft's understanding of the PDB format, and not
LLVM's). To this end, I've added support for dumping injected sources
via DIA. I made a PDB file that used the /natvis option to generate a
test case.

CodeView: Provide a .def file with the register ids

The list of register ids was previously written out in a couple of dirrent
places. This puts it in a .def file and also adds a few more registers (e.g.
the x87 regs) which should lead to more readable dumps, but I didn't include
the whole list since that seems unnecessary.

X86_MC::initLLVMToSEHAndCVRegMapping is pretty ugly, but at least it's not
relying on magic constants anymore. The TODO of using tablegen still stands.

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.
