web-flowRecreate full dag instead of inplace substitution in BasisTranslator (#12195) (#12855) * Recreate full dag instead of inplace substitution in BasisTranslator This commit tweaks the internal logic of the basis translator transpiler pass to do a full dag recreation instead of inplace modification. If only a few operations were to be substituted it would probably be more efficient to do an inplace modification, but in general the basis translator ends up replacing far more operations than not. In such cases just iterating over the dag and rebuilding it is more efficient because the overhead of `apply_operation_back()` is minimal compared to `substitute_node_with_dag()` (although it's higher than `subtitute_node(.., inplace=True)`). * Return boolean together with dag in 'apply_translation' to maintain original 'flow_blocks' logic and fix drawer test. * Remove print --------- Co-authored-by: Elena Peña Tapia <epenatap@gmail.com> (cherry picked from commit 37b334fb7) Co-authored-by: Matthew Treinish <mtreinish@kortar.org>
