Rollup merge of #136746 - wesleywiser:err_dwarf1, r=Urgau
Emit an error if `-Zdwarf-version=1` is requested

DWARF 1 is very different than DWARF 2+[^1] and LLVM does not really seem to support DWARF 1 as Clang does not offer a `-gdwarf-1` flag[^2] and `llc` will just generate DWARF 2 with the version set to 1[^3].

Since this isn't actually supported (and it's not clear it would be useful anyway), report that DWARF 1 is not supported if it is requested.

Also add a help message to the error saying which versions are supported.
