[lld-macho] Fix loading same libraries from both LC_LINKER_OPTION and command line

This fixes https://github.com/llvm/llvm-project/issues/56059 and
https://github.com/llvm/llvm-project/issues/56440. This is inspired by
tapthaker's patch (https://reviews.llvm.org/D127941), and has reused his
test cases. This patch adds an bool "isCommandLineLoad" to indicate
where archives are from. If lld tries to load the same library loaded
previously by LC_LINKER_OPTION from CLI, it will use this
isCommandLineLoad to determine if it should be affected by -all_load &
-ObjC flags. This also prevents -force_load from affecting archives
loaded previously from CLI without such flag, whereas tapthaker's patch
will fail such test case (introduced by
https://reviews.llvm.org/D128025).
