Remove PulseSimulator (Qiskit#1884)

Since 0.12, Qiskit-Aer notices deprecation warnings to use of PulseSimulato. Because 0.13 will be released after +3 months since 0.12 was released, Qiskit-Aer will stop supports of pulse simulation. * first pass at removing pulse simulator * autoformat with black * remove ref to aer pulse in docs * fix lint issues * remove pulse rst * remove pulse tests * add release note * remove open pulse from CMakeLists.txt * remove pulse tests * remove remaining pulse codes --------- Co-authored-by: AngeloDanducci <angelo.danducci.ii@ibm.com>
