Add Rust to CodeView SourceLanguage (CV_CFL_LANG) enum

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.

[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.

[codeview] Decode and dump FP regs from S_FRAMEPROC records

Summary:
There are two registers encoded in the S_FRAMEPROC flags: one for locals
and one for parameters. The encoding is described by the
ExpandEncodedBasePointerReg function in cvinfo.h. Two bits are used to
indicate one of four possible values:

0: no register - Used when there are no variables.
1: SP / standard - Variables are stored relative to the standard SP
for the ISA.
2: FP - Variables are addressed relative to the ISA frame
pointer, i.e. EBP on x86. If realignment is required, parameters
use this. If a dynamic alloca is used, locals will be EBP relative.
3: Alternative - Variables are stored relative to some alternative
third callee-saved register. This is required to address highly
aligned locals when there are dynamic stack adjustments. In this
case, both the incoming SP saved in the standard FP and the current
SP are at some dynamic offset from the locals. LLVM uses ESI in
this case, MSVC uses EBX.

Most of the changes in this patch are to pass around the CPU so that we
can decode these into real, named architectural registers.

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.

[CodeView] Move CodeView YAML code to ObjectYAML.

This is the beginning of an effort to move the codeview yaml
reader / writer into ObjectYAML so that it can be shared.
Currently the only consumer / producer of CodeView YAML is
llvm-pdbdump, but CodeView can exist outside of PDB files, and
indeed is put into object files and passed to the linker to
produce PDB files. Furthermore, there are subtle differences
in the types of records that show up in object file CodeView
vs PDB file CodeView, but they are otherwise 99% the same.

By having this code in ObjectYAML, we can have llvm-pdbdump
reuse this code, while teaching obj2yaml and yaml2obj to use
this syntax for dealing with object files that can contain
CodeView.

This patch only adds support for CodeView type information
to ObjectYAML. Subsequent patches will add support for
CodeView symbol information.
