[ClangLinkerWrapper] Fix -v for newer CMake passing it directly (#188883)

Browse Source 
Summary:
Normally `-v` is version for tools, but it's also verbose for the
linker. CMake tries to identify the linker by passing `-Wl,-v` which
goes to the linker wrapper instead. Make this only print version on
`--version` and forward the other one to the linker so it appears
transparent to the host ABI. A bit of a hack, but it should work.
