Added two parameters to :class:`.GenericBackendV2` to exclude error (`noise_info`) and
pulse channel information (`pulse_channels`) from the construction of the backend. These parameters
are true by default, replicating the initial default behavior of the constructor. A memory-sensitive
user may set these options to `False` to reduce the memory overhead by 40x when transpiling on large-
scale :class:`.GenericBackendV2`.
