     * Allocates a driver-managed buffer with the properties specified by the buffer descriptor

     * as well as the input and output roles.

     *

     * The allocate function must verify its inputs are correct. If there is an error, or if a

     * certain role or property is not supported by the driver, the allocate

     * function must return with an appropriate ErrorStatus, a nullptr as the IBuffer, and 0 as the

     * buffer token. If the allocation is successful, this method must return with ErrorStatus::NONE

     * and the produced IBuffer with a positive token identifying the allocated buffer. A successful

     * allocation must accommodate all of the specified roles and buffer properties.

     *

     * The buffer is allocated to an uninitialized state. An uninitialized buffer may only be used

     * in ways that are specified by outputRoles. A buffer is initialized after it is used as an

     * output in a successful execution, or after a successful invocation of IBuffer::copyFrom on

     * the buffer. An initialized buffer may be used according to all roles specified in inputRoles

     * and outputRoles. A buffer will return to the uninitialized state if it is used as an output

     * in a failed execution, or after a failed invocation of IBuffer::copyFrom on the buffer.

     *

     * The dimensions of the buffer can be deduced from the buffer descriptor as well as the

     * dimensions of the corresponding model operands of the input and output roles. The dimensions

     * or rank of the buffer may be unknown at this stage. As such, some driver services may only

     * create a placeholder and defer the actual allocation until execution time. Note that the

     * same buffer may be used for different shapes of outputs on different executions. When the

     * buffer is used as an input, the input shape must be the same as the output shape from the

     * last execution using this buffer as an output.

     *

     * The driver must apply proper validatation upon every usage of the buffer, and must fail the

     * execution immediately if the usage is illegal.

     *

     * @param desc A buffer descriptor specifying the properties of the buffer to allocate.

     * @param preparedModels A vector of IPreparedModel objects. Must only contain IPreparedModel

     *     objects from the same IDevice as this method is being invoked on.

     * @param inputRoles A vector of roles with each specifying an input to a prepared model.

     * @param outputRoles A vector of roles with each specifying an output to a prepared model.

     *     Each role specified in inputRoles and outputRoles must be unique. The corresponding

     *     model operands of the roles must have the same OperandType, scale, zero point, and

     *     ExtraParams. The dimensions of the operands and the dimensions specified in the buffer

     *     descriptor must be compatible with each other. Two dimensions are incompatible if there

     *     is at least one axis that is fully specified in both but has different values.

     * @return status Error status of the buffer allocation. Must be:

     *     - NONE if successful

     *     - DEVICE_UNAVAILABLE if driver is offline or busy

     *     - GENERAL_FAILURE if a certain buffer property or a certain role is not supported,

     *       or if there is an unspecified error

     *     - INVALID_ARGUMENT if one of the input arguments is invalid

     * @return buffer The allocated IBuffer object. If the buffer was unable to be allocated

     *     due to an error, nullptr must be returned.

     * @return token A positive token identifying the allocated buffer. The same token will be

     *     provided when referencing the buffer as one of the memory pools in the request of an

     *     execution. The token must not collide with the tokens of other IBuffer objects that are

     *     currently alive in the same driver service. If the buffer was unable to be allocated

     *     due to an error, the token must be 0.
