Support standalone `Var`s in OQ3 exporter (#12308)

* Support standalone `Var`s in OQ3 exporter

This adds the remaining support needed for the OpenQASM 3 exporter to
support standalone variables.  The way the circuit model handles
closures over these variables makes it much easier to support these than
it was to handle free-form control-flow operations.

This PR somewhat refactors small parts of the exporter to better isolate
the "top-level program" statement construction and analysis from the
"build a scoped set of instructions" logic, which makes it rather easier
to handle things like declaring IO variables only in the global scope,
but locally declared variables in _all_ relevant scopes.

* Remove references to QSS

* Clarify comment about forward declarations

* Add test for parameter/gate clash resolution
