  [CIR] Support zero/one result trivial operation lower via tablegen (#203183)

### summary

Lower zero result operation have been supported in this PR:
https://github.com/llvm/llvm-project/pull/202273

In this PR, the lowering of operations with zero-result and one-result
is changed to be automatically lowered via TableGen. This helps reduce
the size of the file
`clang/lib/CIR/Lowering/DirectToLLVM/LowerToLLVM.cpp`

#### test

I thought existing lower tests can cover this PR, so I didn't add more
tests.
