[Reland] Detect against invalid variant index for LibStdC++ std::variant data formatters (#69614)
This is relanding of https://github.com/llvm/llvm-project/pull/69253.
`TestTemplatePackArgs.py` is passing now.
https://github.com/llvm/llvm-project/pull/68012/files added new data
formatters for LibStdC++ std::variant.
However, this formatter can crash if std::variant's index field has
invalid value (exceeds the number of template arguments).
This can happen if the current IP stops at a place std::variant is not
initialized yet.
This patch fixes the crash by ensuring the index is a valid value and
fix GetNthTemplateArgument() to make sure it is not crashing.
