When a protocol witness thunk is formed to a serialised protocol
containing an `async` function, the async function pointer to the
conformance needs to be made public due to a SIL Verifier check failure
(reference to a non-fragile function from within a public fragile
function). Add a stop-gap solution of rolling an extra emission for a
private symbol as a public symbol to avoid the error (the underlying
issue has been open for ~6y and counting as of this commit).
This was identified by swift-package-manager (#64900).
Thanks to @DougGregor and @aschwaighofer for the discussion on this!
Deployment target can be set before the introduction of a moved symbol. When that
happens, using the introductory version in the $ld$previous symbol could lead to ld
not redirecting the linkage path to the original dylib, which is a mistake when running
the App on newer OSs when the original dylib does exist.

`hasValue` -> `has_value`
`map` -> `transform`
The old API will be deprecated in the rebranch.
To avoid merge conflicts, use the new API already in the main branch.

TBD files contain a section reserved for obj-c classes. Previously,
TBDGen was adding symbols with this + normal globals with objc class
prefixes. This patch removes the extra globals being added.
This also accounts for this behavior for `validate-tbd-against-ir`
checking.

The relationship between the code in these two libraries was fundamentally circular, indicating that they should not have been split. With other changes that I'm making to remove circular dependencies from the CMake build graph I eventually uncovered that these two libraries were required to link each other circularly, but that had been hidden by other cycles in the build graph previously.
