[llvm-lib] Add /llvmlibindex:no to disable writing an index (#120596)
This can be used with /llvmlibthin to create thin archives without an
index, which is a prerequisite for porting
https://reviews.llvm.org/D117284 to lld-link.
Creating files like this is already possible with `llvm-ar rcS`, so this
doesn't add additional problems.
