CUST-5221: add "destroy" with json-body to booking deletion

[googsvg]

Added support for sending a JSON body with booking cancellation requests in the Java SDK.

Bookings.destroy() now has request-body overloads that accept DestroyBookingRequest and forward cancellation_reason through the SDK, while the existing legacy destroy(bookingId, queryParams, overrides) overload remains unchanged for backward compatibility. NylasClient.executeDelete() was extended with a body-capable overload to support this behavior.
