  [NVPTX] Fix DwarfFrameBase construction (#101000)

The `{0}` here was initializing the first union member `Register`,
rather than the union member used by CFA, which is `Offset`. Prior to
https://github.com/llvm/llvm-project/pull/99263 this was harmless, but
now they have different layout, leading to test failures on some
platforms (at least i686 and s390x).

(cherry picked from commit 842a332f11f53c698fa0560505e533ecdca28876)
