fix(ivy): fix bug with banana-in-a-box expressions in nested templates (#25321)

Inside of a nested template, an attempt to generate code for a banana-
in-a-box expression would cause a crash in the _AstToIrVisitor, as it
was not handling the case where a write would be generated to a local
variable.

This change supports such a mode of operation.
