[LinkerWrapper] Do not extract globals with no offloading language
The linker wrapper needs to reinvent its own special static library
handling for static libraries containing fatbinaries. This is primarily
because offloading languages expect certain global symbols to be visible
to the host so we must consider them used symbols. However we should be
able to remove this requirement if we are linking in "freestanding" code
that was not created by an offloading language.
The motivation for this is to support the work-in-progress `libc` for
GPUs. It is provided as a static library with no offloading language
set. This logic will let us only import used `libc` symbols always.
