This reverts commit aa495214b39d475bab24b468de7a7c676ce9e366. As discussed in https://github.com/llvm/llvm-project/issues/53475 this patch allows for using LLD-as-a-lib. It also lets clients link only the drivers that they want (see unit tests). This also adds the unit test infra as in the other LLVM projects. Among the test coverage, I've added the original issue from @krzysz00, see: https://github.com/ROCmSoftwarePlatform/D108850-lld-bug-reproduction Important note: this doesn't allow (yet) linking in parallel. This will come a bit later hopefully, in subsequent patches, for COFF at least. Differential revision: https://reviews.llvm.org/D119049

// This test shows a typical case where all LLD drivers are linked into the

// except that here we cleanup the internal LLD memory context after each call.
