Alex MacLean de7438e472 [NVPTX] Auto-Upgrade some nvvm.annotations to attributes (#119261) ...

Add a new AutoUpgrade function to convert some legacy nvvm.annotations
metadata to function level attributes. These attributes are quicker to
look-up so improve compile time and are more idiomatic than using
metadata which should not include required information that changes the
meaning of the program.

Currently supported annotations are:

- !"kernel" -> ptx_kernel calling convention
- !"align" -> alignstack parameter attributes (return not yet supported)
