Fix build with --no-jlinking

Don't allow null values to be passed to the `register` method of
`RuntimeJNIAccess` and `RuntimeReflection`. Since these are public APIs
GraalVM should either handle null values (by ignoring them in this case)
or throw a `NullPointerException` before creating an asynchronous task
to perform the registration in the analysis, which then results in
`NullPointerException`s being thrown later when it's no longer possible
to understand where the null value originate from.

Not before the register methods, which can miss cases, nor later on in a runnable.

Backport: [GR-49816] Throw exception for null pointers passed to RuntimeJNIAccess / RuntimeReflection register methods

…23.1

This is a no-op change, but makes downstream Mandrel 23.1
be in sync with the upstream community repo. It makes it
easier to spot any downstream only patches if the diff
to upstream is minimal.
