Perl_scalarvoid: turn OP_STUB into OP_NULL
An OP_STUB in void context is functionally identical to an OP_NULL.
It's straightforward and safe to transform an OP_STUB into an OP_NULL
by adding an extra `case` within `Perl_scalarvoid`. In doing so:
* The redundant OPs are more likely to be omitted from the op_next chain.
* The OP tree is more consistent with `assert` expectations in `Perl_rpeep`.
(The programs in GH #17228 no longer trigger assertions.)
