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.

It appears for Swift there was confusing errors when trying to parse APINotes, when libAPINotes and libInterfaceStub are linked, they both export symbol
`__ZN4llvm4yaml7yamlizeINS_12VersionTupleEEENSt3__19enable_ifIXsr16has_ScalarTraitsIT_EE5valueEvE4typeERNS0_2IOERS5_bRNS0_12EmptyContextE`, and discovered
same symbol defined within llvm-ifs.
This consolidates the boilerplate into YAMLTraits and defers the specific validation in reading the whole input.

Prior to this change the clang interface stubs format resembled
something ending with a symbol list like this:
Symbols:
a: { Type: Func }
This was problematic because we didn't actually want a map format and
also because we didn't like that an empty symbol list required
"Symbols: {}". That is to say without the empty {} llvm-ifs would crash
on an empty list.
With this new format it is much more clear which field is the symbol
name, and instead the [] that is used to express an empty symbol vector
is optional, ie:
Symbols:
- { Name: a, Type: Func }
or
Symbols: []
or
Symbols:
This further diverges the format from existing llvm-elftapi. This is a
good thing because although the format originally came from the same
place, they are not the same in any way.

This is how it should've been and brings it more in line with
std::string_view. There should be no functional change here.
This is mostly mechanical from a custom clang-tidy check, with a lot of
manual fixups. It uncovers a lot of minor inefficiencies.
This doesn't actually modify StringRef yet, I'll do that in a follow-up.
The following changes enable llvm-ifs to handle the following merge conflicts:
* Weak + Strong symbol merging for the same symbol
* empty vs non-empty triple field
* empty vs non-empty object file format

Summary:
This is a patch for updating TextAPI/Macho to read in targets as opposed to arch/platform.
This is because in previous versions tbd files only supported a single platform but that is no longer the case,
so, now its tracked by unique triples.
This precedes a seperate patch that will add the TBD-v4 format

This is a continuation of the YAML library error reporting
refactoring/improvement and the idea by itself was mentioned
in the following thread:
https://reviews.llvm.org/D67182?id=218714#inline-603404
This performs a cleanup of all object emitters in the library.
It allows using the custom one provided by the caller.
One of the nice things is that each tool can now print its tool name,
e.g: "yaml2obj: error: <text>"
Also, the code became a bit simpler.

It was pointed out that I had hard-coded PlatformKind. This is rectifying that.

gcc produces the error:
error: specialization of
‘template<class T, class Enable> struct llvm::yaml::ScalarTraits’ in
different namespace
For all specializations outside of llvm::yaml. So I added llvm::yaml to these
specializations to fix the errors on the bots building with gcc (/usr/bin/c++).

This tool merges interface stub files to produce a merged interface stub file
or a stub library. Currently it for stub library generation it can produce an
ELF .so stub file, or a TBD file (experimental). It will be used by the clang
-emit-interface-stubs compilation pipeline to merge and assemble the per-CU
stub files into a stub library.
The new IFS format is as follows:
--- !experimental-ifs-v1
IfsVersion: 1.0
Triple: <llvm triple>
ObjectFileFormat: <ELF | TBD>
Symbols:
_ZSymbolName: { Type: <type>, etc... }
