feat: Add re-exports for ComposablePass definitions (#1941)

Adds re-exports for `ComposablePass` and `PassScope` definitions, to
help with migrating before we remove them from `hugr`. See
#1705.

+"""Scope configuration for a pass.
+
+A `PassScope` defines the parts of a HUGR that a pass should be applied to, and
+which parts is it allowed to modify. Each variant defines three properties: `root`,
+`preserve_interface` and `recursive`.
+
+From these, `regions` and `in_scope` can be derived.
+
+A pass will always optimize the entrypoint region, unless the entrypoint is the
