* Modify UNet2DConditionModel

- allow skipping mid_block

- adding a norm_group_size argument so that we can set the `num_groups` for group norm using `num_channels//norm_group_size`

- allow user to set dimension for the timestep embedding (`time_embed_dim`)

- the kernel_size for `conv_in` and `conv_out` is now configurable

- add random fourier feature layer (`GaussianFourierProjection`) for `time_proj`

- allow user to add the time and class embeddings before passing through the projection layer together - `time_embedding(t_emb + class_label))`

- added 2 arguments `attn1_types` and `attn2_types`

  * currently we have argument `only_cross_attention`: when it's set to `True`, we will have a to the
`BasicTransformerBlock` block with 2 cross-attention , otherwise we
get a self-attention followed by a cross-attention; in k-upscaler, we need to have blocks that include just one cross-attention, or self-attention -> cross-attention;
so I added `attn1_types` and `attn2_types` to the unet's argument list to allow user specify the attention types for the 2 positions in each block;  note that I stil kept
the `only_cross_attention` argument for unet for easy configuration, but it will be converted to `attn1_type` and `attn2_type` when passing down to the down blocks

- the position of downsample layer and upsample layer is now configurable

- in k-upscaler unet, there is only one skip connection per each up/down block (instead of each layer in stable diffusion unet), added `skip_freq = "block"` to support
this use case

- if user passes attention_mask to unet, it will prepare the mask and pass a flag to cross attention processer to skip the `prepare_attention_mask` step
inside cross attention block

add up/down blocks for k-upscaler

modify CrossAttention class

- make the `dropout` layer in `to_out` optional

- `use_conv_proj` - use conv instead of linear for all projection layers (i.e. `to_q`, `to_k`, `to_v`, `to_out`) whenever possible. note that when it's used to do cross
attention, to_k, to_v has to be linear because the `encoder_hidden_states` is not 2d

- `cross_attention_norm` - add an optional layernorm on encoder_hidden_states

- `attention_dropout`: add an optional dropout on attention score

adapt BasicTransformerBlock

- add an ada groupnorm layer  to conditioning attention input with timestep embedding

- allow skipping the FeedForward layer in between the attentions

- replaced the only_cross_attention argument with attn1_type and attn2_type for more flexible configuration

update timestep embedding: add new act_fn  gelu and an optional act_2

modified ResnetBlock2D

- refactored with AdaGroupNorm class (the timestep scale shift normalization)

- add `mid_channel` argument - allow the first conv to have a different output dimension from the second conv

- add option to use input AdaGroupNorm on the input instead of groupnorm

- add options to add a dropout layer after each conv

- allow user to set the bias in conv_shortcut (needed for k-upscaler)

- add gelu

re: https://github.com/huggingface/diffusers/issues/1857

We relax some of the checks to deal with unclip reproducibility issues. Mainly by checking the average pixel difference (measured w/in 0-255) instead of the max pixel difference (measured w/in 0-1).

- [x] add mixin to UnCLIPPipelineFastTests
- [x] add mixin to UnCLIPImageVariationPipelineFastTests
- [x] Move UnCLIPPipeline flags in mixin to base class
- [x] Small MPS fixes for F.pad and F.interpolate
- [x] Made test unCLIP model's dimensions smaller to run tests faster
