Currently unknown keys when inputting mapping traits have the location set to the Value.
Example:
```
YAML:1:14: error: unknown key 'UnknownKey'
{UnknownKey: SomeValue}
^~~~~~~~~
```
This is unhelpful for a user as it draws them to fix the wrong item.

Summary:
[llvm][TextAPI] adding inlining reexported libraries support
* this patch adds reader/writer support for MachO tbd files.
The usecase is to represent reexported libraries in top level library
that won't need to exist for linker indirection because all of the
needed content will be inlined in the same document.

Same as D73328 but for TBD_V4. One notable tidbit is that the swift abi
version for swift 1 & 2 is emitted as a float which is considered
invalid input.

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.
TAPI currently lacks a way to emit the macCatalyst platform. For TBD_V3
is does support zippered frameworks given that both macOS and
macCatalyst are part of the PlatformSet.

The existing unit tests cover a wide variety of reading TBD files but
lack coverages on the writing side. Case in point is the macCatalyst
case which we're able to read, but not write.
This patch extends the unit test dealing with valid input to write their

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

llvm::yaml::Output::paddedKey unconditionally outputs spaces, which
are superfluous if the value to be dumped is a sequence or map.
Change `bool NeedsNewLine` to `StringRef Padding` so that it can be
overridden to `\n` if the value is a sequence or map.
An empty map/sequence is special. It is printed as `{}` or `[]` without
a newline, while a non-empty map/sequence follows a newline. To handle
this distinction, add another variable `PaddingBeforeContainer` and does
the special handling in endMapping/endSequence.

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.

TextAPI is a library and accompanying tool that allows conversion between binary shared object stubs and textual counterparts. The motivations and uses cases for this are explained thoroughly in the llvm-dev proposal [1]. This initial commit proposes a potential structure for the TAPI library, also including support for reading/writing text-based ELF stubs (.tbe) in addition to preliminary support for reading binary ELF files. The goal for this patch is to ensure the project architecture appropriately welcomes integration of Mach-O stubbing from Apple's TAPI [2].
Added:
- TextAPI library
- .tbe read support
- .tbe write (to raw_ostream) support
