[NVPTX][NFC] Remove unneeded declarations in test

[hdelan]

Only the bf16 declarations are needed, as only they are lowered in AutoUpgrade.cpp.
f16 and other builtins have LLVM intrinsics already defined.

Are these declarations tested elsewhere?

It's not clear to me that the fix is removing them, vs adding missing tests for them.

These declarations that I have removed are used and their PTX lowering tested in this file. But they don't need to be declared in the test file since they are LLVM intrinsics. By contrast the bf16 llvm. declarations are needed since the bf16 funcs are not real LLVM intrinsics. Their lowerings are hoisted here
