RFR: 8282143: Objects.requireNonNull should be ForceInline [v2]

[Quan Anh Mai]

> Hi,
> 
> `Objects.requireNonNull` may fail to be inlined. The call is expensive and may lead to objects escaping to the heap while the null check is cheap and is often elided. I have observed this when using the vector API when a call to `Objects.requireNonNull` leads to vectors being materialised in a hot loop.
> 
> Should the other `requireNonNull` be `ForceInline` as well?

> Thank you very much.
