[NVPTX] Allow more argument integer types, such as i256 and i96 (#154824)
The refactoring of ComputePTXValueVTs in #154476 caused the complier to
no longer crash when lowering i256 and i96. This has caused a few tests
to unexpectedly pass.

Update these tests and tweak how we emit parameter declarations to
correctly lower these types.
