Create writer for new JSON format.
The new JSON format allows practically all attributes to be defined per
target in a universal library however the internal representation only
allows one for the time being. For now the write will always write those
attributes as default available for all targets (install name,
compatability & current version, swift abi, flags e.g. flatnamepace &
app exenstion safety)

f09cf34d00 [Support] Move TargetParsers to new component
This is a fairly large changeset, but it can be broken into a few
pieces:
- `llvm/Support/*TargetParser*` are all moved from the LLVM Support
  component into a new LLVM Component called "TargetParser". This
  potentially enables using tablegen to maintain this information, as
  is shown in https://reviews.llvm.org/D137517. This cannot currently
  be done, as llvm-tblgen relies on LLVM's Support component.
- This also moves two files from Support which use and depend on
  information in the TargetParser:
  - `llvm/Support/Host.{h,cpp}` which contains functions for inspecting
    the current Host machine for info about it, primarily to support
    getting the host triple, but also for `-mcpu=native` support in e.g.
    Clang. This is fairly tightly intertwined with the information in
    `X86TargetParser.h`, so keeping them in the same component makes
    sense.
  - `llvm/ADT/Triple.h` and `llvm/Support/Triple.cpp`, which contains
    the target triple parser and representation. This is very intertwined
    with the Arm target parser, because the arm architecture version
    appears in canonical triples on arm platforms.
- I moved the relevant unittests to their own directory.

And so, we end up with a single component that has all the information
about the following, which to me seems like a unified component:
- Triples that LLVM Knows about
- Architecture names and CPUs that LLVM knows about
- CPU detection logic for LLVM

Given this, I have also moved `RISCVISAInfo.h` into this component, as
it seems to me to be part of that same set of functionality.

If you get link errors in your components after this patch, you likely
need to add TargetParser into LLVM_LINK_COMPONENTS in CMake.

9a2e2de15f [lld-macho] Change loadReexport to handle the case where a TAPI re-exports to reference documents nested within other TBD.
Currently, it was delibrately impleneted to not handle this case, but as it has turnt out, we need this feature.
The concrete use case is
       `System/Library/Frameworks/Cocoa.framework/Versions/A/Cocoa` reexports
               /System/Library/Frameworks/AppKit.framework/Versions/C/AppKit , which then rexports
                    /System/Library/PrivateFrameworks/UIFoundation.framework/Versions/A/UIFoundation

The current implemention uses a global currentTopLevelTapi, which is not reset until it finishes loading the whole tree.
This is a problem because if the top-level is set to Cocoa, then when we get to UIFoundation, it will try to find UIFoundation in the current top level, which is Cocoa and will not find it.

The right thing should be:
 - When loading a library from a TBD file, re-exports need to be looked up in the auxiliary documents within the same TBD.
 - When loading from an actual dylib, no additional TBD documents need to be examined.
 - In no case does a re-export mentioned in one TBD file need to be looked up in a document in an auxiliary document from a different TBD file

No longer rely on an external tool to build the llvm component layout.

Instead, leverage the existing `add_llvm_componentlibrary` cmake function and
introduce `add_llvm_component_group` to accurately describe component behavior.

These function store extra properties in the created targets. These properties
are processed once all components are defined to resolve library dependencies
and produce the header expected by llvm-config.
