`module.map` as a module map name has been discouraged since 2014, and
Clang will soon warn on its usage. This patch renames all instances of
`module.map` in the Swift tests to `module.modulemap` in preparation
for this change to Clang.

The `call` argument to `diagnoseDeclAsyncAvailability()` may be `nullptr` when the structure of the AST prevents `getEnclosingApplyExpr()` from finding the enclosing apply. The diagnostics implementation introduced with https://github.com/apple/swift/pull/60663 needs to tollerate this, similar to the rest of `diagnoseDeclAsyncAvailability()`.

We used to attach this diagnostic to the implicit decl. Now, attach it to the enclosing decl and offer an extra note that states the availability of the implicit declaration that is at conflict with the availability of the enclosing scope.

Implicitly add the @completionHandlerAsync attribute for ObjCMethodDecl
that have a completion handler. Adds a link from the non-async to the
async function for use in diagnostics and refactorings.
