Add new transpiler exception class for too many qubits (#11241)

* Add new transpiler exception class for too many qubits

This commit adds a new exception class for when the transpiler is
given a circuit too many qubits for a given backend. Previously the
generic TranspilerError was raised for this, but it made it difficult
for downstream users to catch as it wasn't easy to differentiate this
error condition from other TranspilerError exceptions. There isn't any
backwards compatibility issues with this because the new
CircuitToWideForTarget class is a subclass of TranspilerError so any of
the previous catches for TranspilerError will still catch this.

* Fix typo in class name

* Make test check more specific exception type

* Replace :class: with :exc: in release note
