[WIP][AMDGPU] Split isInlinableLiteral16 into three and call the specific version if possible
The current implementation of `isInlinableLiteral16` assumes, a 16-bit inlinable literal is either an i16 or a fp16. This is not always true because of bf16. However, we can't tell fp16 and bf16 apart by just looking at the value. This patch tries to split `isInlinableLiteral16` into three versions, i16, fp16, bf16 respectively, and call the corresponding version. This patch is based on #81282. The current status is, only two uses of original `isInlinableLiteral16` are still there. We need to add an extra argument to indicate the type of the operand the immediate corresponds to. This will also require the change of the function signature of the two callers.
