Use static archives as an alternative to object merging
Unfortunately, `lld`'s COFF backend does not currently support object
merging. With ld.bfd having broken support for high image-load base
addresses, it's necessary to find an alternative. Here I introduce
support in the driver for generating static archives, which we use on
Windows instead of object merging.
Closes #21068.
