[lld-macho] Make it possible to re-export .tbd files Two things needed fixing for that to work: 1. getName() no longer returns null for DylibFiles constructed from TAPIs 2. markSubLibrary() now accepts .tbd as a possible extension Differential Revision: https://reviews.llvm.org/D86180

[lld-macho] Handle TAPI and regular re-exports uniformly The re-exports list in a TAPI document can either refer to other inlined TAPI documents, or to on-disk files (which may themselves be TBD or regular files.) Similarly, the re-exports of a regular dylib can refer to a TBD file. Differential Revision: https://reviews.llvm.org/D85404

[lld-macho] Implement `-no_implicit_dylibs` Dylibs that are "public" -- i.e. top-level system libraries -- are considered implicitly linked when another library re-exports them. That is, we should load them & bind directly to their symbols instead of via their re-exporting umbrella library. This diff implements that behavior by default, as well as an opt-out flag. In theory, this is just a performance optimization, but in practice it seems that it's needed for correctness. Fixes llvm.org/PR48395.
