  [AMDGPU] Replace `isInlinableLiteral16` with specific version (#84402)

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 splits `isInlinableLiteral16` into three versions,
`i16`,
`fp16`, `bf16` respectively, and call the corresponding version.
