[lworld] RFR: 8352647: [lworld] Remove larval InlineTypeNode in Unsafe intrinsics [v3]

[Quan Anh Mai]

> Hi,
> 
> As a step of #1405, I would like to remove the usage of larval value objects in `Unsafe` intrinsics. This patch also tries to make sure that `Unsafe::makePrivateBuffer` and `Unsafe::finishPrivateBuffer` are always inlined, so that larval objects do not cross call boundaries except for invoking object constructors.
> 
> Please take a look and review this PR, thanks a lot.
