Add PlatformDependent* methods that are needed by io_uring (#10744)

Motivation:

ddebc10 added a few adjustments that are needed by io_uring that we will add as an incubator repository. Unfortunally we missed the changed in PlatformDependent*.

Modifications:

Add missing methods

Result:

Be able to compile io_uring code against core netty
