YJIT: Initialize locals in ISeqs defined with `...`
Backport of GH-12660:
Previously, callers of forwardable ISeqs moved the stack pointer up
without writing to the stack. If there happens to be a stale value in
the area skipped over, it could crash due to "try to mark T_NONE". Also,
the uninitialized local variables were observable through `binding`.
Initialize the locals to nil.
