Adding a list of model's param size( MB ) and layernum of models in torchvision with a standard input shape like 3,224,224

📚 The doc issue

Torchvision is lacking a table of models' size and layernum

Suggest a potential alternative/fix

Recently, I'm working on choosing some models from torchvision.
And as we all know, a model's size and layers are critical to many aspects.
Especially for beginners who don't familiar with these models, this table can help a lot.
If you think this is necessary, I'm glad to help collect these models' size and layernum and pull a request

Thanks for the proposal. I agree.

@NicolasHug We should consider adding the model size in the meta-data of the new model API and expose it via the documentation.
