[LLD] [COFF] Add tests to observe details about LTO and __imp_ prefixes. NFC. (#72764) The commit 3ab6209a3f93bdbeec8e9b9fcc00a9a4980915ff had the undesired effect of retaining every `__imp_` symbol, even if it isn't referenced in any way. Add a testcase to observe this behaviour, to serve as a reference point if this behaviour were to be improved later. Port the testcase from b963c0b658cc54b370832df4f5a3d63fd69da334 from the llvm/LTO testsuite into LLD as a preparation for changing that fix; the moved testcase has a comment for one case which doesn't work currently. The testcase is ported mostly as is, but with symbol mangling simplified, rewriting function names from MSVC C++ mangling to plain C, and unnecessary debug info is removed. Add a case of a dllimported data symbol, in addition to the existing call of a dllimported function. Also extend the testcase to test combinations of both regular object files and LTO objects. Leave out one combination which currently fails, with a comment. GitOrigin-RevId: 6a323e7ec3478e633ba85ce6c274f02d0b31299b
