New features

• Add new Keras rematerialization API: keras.RematScope and keras.remat. It can be used to turn on rematerizaliation for certain layers in fine-grained manner, e.g. only for layers larger than a certain size, or for a specific set of layers, or only for activations.
• Increase op coverage for OpenVINO backend.
• New operations:
  • keras.ops.rot90
  • keras.ops.rearrange (Einops-style)
  • keras.ops.signbit
  • keras.ops.polar
  • keras.ops.image.perspective_transform
  • keras.ops.image.gaussian_blur
• New layers:
  • keras.layers.RMSNormalization
  • keras.layers.AugMix
  • keras.layers.CutMix
  • keras.layers.RandomInvert
  • keras.layers.RandomErasing
  • keras.layers.RandomGaussianBlur
  • keras.layers.RandomPerspective
• Minor additions:
  • Add support for dtype argument to JaxLayer and FlaxLayer layers
  • Add boolean input support to BinaryAccuracy metric
  • Add antialias argument to keras.layers.Resizing layer.
• Security fix: disallow object pickling in saved npz model files (numpy format). Thanks to Peng Zhou for reporting the vulnerability.
