Implement PauliStringPhasorGate (quantumlib#4696)

BREAKING CHANGE: PauliStringPhasor no longer inherits from PauliStringGateOperation. Implements PauliStringPhasor in terms of a GateOperation on a new class PauliStringPhasorGate. Mostly involved moving existing functions from the operation to the gate, and then having the operation call those methods under the hood. Closes quantumlib#1561, xref quantumlib#4683 @tanujkhattar
