Improved clifford-T pipeline (#15625)

* initial experiment

* Adding filter_fn argument to Collect1qRuns and Collect2qBlocks

* Initial implementation

* cleanup

* experiment

* Further improving Clifford+T pipeline

* adding approximation_degree; fix test

* improve CliffordTOpt

* fixing failing tests

* fixes

* change tau to two_pi

* added more functions for canonicalization and included code for reusing synthesis of same angles

* canonical representation corrections

* removes square brackets

* added a param test

* angle approximation logic implemented and epsilon reduced

* documentation added and epsilon modified to approximation degree

* added more tests

* documentation corrections

* improve angle canonicalization test

* lint fix

* Restructuring the Clifford+T code: fully separating Clifford+T compilation
from the standard (near-term) compilation.

* tuning of Clifford+T pipeline

* fix to CircuitData vs PyCircuitData after merge-with-main

* update to loop condition + ruff

* Updating equivalence library with better decompositions of T/Tdg gates in terms of each other

This also required adding Z = Sdg Sdg (in addition to the existing Z = S S).

* Tuning Clifford+T pipeline

The translation to Clifford+T now uses all Clifford+T gates, and the loop in
the optimization stage now optimizes Clifford+T circuits. The post-loop
contains translation to the ... (continued)
